22. CARD_CTL (eMMC, SD, SDIO)

22.1 Introduction

MMC is the abbreviation of Multi-Media Card. It is a non-volatile memory device that is small in size, large in capacity, low in power consumption, and fast in transmission. It is widely used in consumer electronics.
eMMC is an abbreviation of embedded Multi-Media Card. The embedded memory standard specifications established by the MMC Association are mainly for mobile device products, such as mobile phones...etc. It has been developed on the basis of MMC.
The SD card is a Secure Digital Memory Card, it is also developed on the basis of MMC, adding two main features: SD card emphasizes the security of data, can set the stored usage rights to prevent data from being copied by others; another feature is the transmission speed faster than the MMC2.11 version.
SDIO evolved from SD, emphasizing the interface (IO, Input / Output), no longer pay attention to the specific form of the other end (can be WIFI devices, Bluetooth devices, GPS, etc.).
MMC has evolved different specifications based on different considerations such as MMC, SD, microSD, SDIO, and eMMC. Although the squandering is fascinating, its essence is still the same. This is why the Linux kernel uses the MMC subsystem to manage MMC, SD, SDIO and other devices.

The SP7021 Card Controller (CARD_CTL) supports card type spec reach eMMC4.41, SD2.0 and SDIO2.0.
eMMC supports types that if it's densities < 2G, the block length in 1~512 byte and if it's densities > 2G, the block length is 512 byte. The EMMC supports speed mode include default speed 0~26MHZ, high speed SDR 0~52MHZ and high speed DDR 0~52MHZ. The theoretical speed of data rate is up to 104MB/s.
SD supports SDSC, SDHC and SDXC three types SDcard. The SD/SDIO support speed mode include default speed 0~25MHZ and high speed SDR 0~50MHZ. The theoretical speed of data rate is up to 25MB/s.
The SP7021 card controller control registers locate at RGST table Group118~120 (memory map in 0x9C003B00~0x9C003C7F) for EMMC module, Group125~129 (memory map in 0x9C003E80~0x9C0040FF) for SDCARD module and Group264~268 (memory map in 0x9C008400~0x9C00867F) for SDIO module.

22.3 Data Transfer Format

According 1 bit, 4 bit and 8bit mode with trigger in rising edge or both edge, the data transfer have 5 modes. (8 bit mode only be support in EMMC case)

22.3.1 1 bit Bus SDR

1 bit Bus SDR (Single Data Rate): The rising edge sampling can be done by simply using one data signal pin (Data 0). Please refer to figure 22-2.

Figure 22-2 1 bit Bus SDR Data Format

22.3.2 4 bit Bus SDR

4 bit Bus SDR: With rising edge sampling, four data signal pins are required (Data 0 ~ Data 3). Please refer to figure 22-3.

Figure 22-3 4 bit Bus SDR Data Format

22.3.3 8 bit Bus SDR

8 bit Bus SDR: With rising edge sampling, it need to use eight data signal pins (Data 0 ~ Data 7)

Figure 22-4 8 bit Bus SDR Data Format

22.3.4 4 bit Bus DDR

4 bit Bus DDR (Double Data Rate): Block and CRC are sampled at the rising and falling edges of CLK, while the start and end bits are sampled only at the rising edge. Please refer to figure 22-4.

Figure 22-5 4 bit Bus DDR Data Format

22.3.5 8 bit Bus DDR

8 bit Bus DDR (Double Data Rate): Using eight data signal pins (Data 0 ~ Data 7), the data transfer mode is like 4 bit Bus DDR. Please refer to figure 22-5.

Figure 22-6 8 bit Bus DDR Data Format

22.4 Data Transfer Mode

The EMMC module supports PIO/DMA/HWDMA mode. Please refer to register map chapter for the setting.
The SD/SDIO module only support PIO and DMA mode. Please refer to register map chapter for the setting.

22.5 Function Output Port Setting

When the Group1.1 register bit5 set to "1", the EMMC function port will output to SP7021 pin88~97.
When the Group1.1 register bit6 set to "1", the SDCARD function port will output to SP7021 pin81~86.
The SDIO function port can be output to any pins of GPIO port1~8 by set Group2.11~2.13 registers. (Please refer to chapter5 for detail pinmux setting)

22.6 Baud Rate Generation

The baud rate setting for EMMC/SD/SDIO modules are SDCLK = DPLL_CLK / (sdfqsel + 1).
The sdfqsel value can be set in Group119.4[31:20], Group126.17[11:0] and Group265.17[11:0] for EMMC, SD and SDIO modules.

22.7 Adjust Timing Principle

The basic principle is to offset the latency caused by path delay and device output delay by configuring the three parameters clk_delay, wr_delay, and rd_delay. It should be noted that EMMC/SD/SDIO should distinguish between default speed and high speed during TX operation. When RX is operated, only the SD/SDIO needs to distinguish between default speed and high speed. EMMC does not distinguish between RX and high speed. The adjust timing principle as below description and figure 22-7&8 show the Default speed SDR mode write and read delay timing status.

SD/SDIO/EMMC default speed
- write operation(The controller is sent with the negative edge SD_CLK, and the device is sampled using the positive edge SD_CLK)
  - When path_clk_delay > path_data_delay, path_data_delay+wr_delay=path_clk_delay
  - When path_clk_delay < path_data_delay, path_clk_delay+clk_delay=path_data_delay
- read operation(The controller samples with negative edge SD_CLK, and the device sends with positive edge SD_CLK)
  - path_clk_delay + Tout_delay + path_data_delay = rd_delay +SD_CLK/2
SD/SDIO/EMMC high speed
- write operation(The controller is sent with the positive edge SD_CLK, and the device is sampled with the positive edge SD_CLK)
  - path_data_delay+wr_delay=path_clk_delay + SD_CLK/2
- read operation(The controller is sampled with positive edge SD_CLK and the device is sent with positive edge SD_CLK)
  - path_clk_delay + Tout_delay + path_data_delay = rd_delay

Figure 22-7 Default speed SDR mode write delay timing

Figure 22-8 Default speed SDR mode read delay timing
Please refer to register map chapter for the clock/write/read delay timing setting.

22.8 CARD_CTL Interrupts

EMMC_CTL support three type interrupts which include pio_int, dma_int and hw_dma _int. SD/SDIO only support two type interrupts which include pio_int and dma_int.

HW DMA can be enable at Group118.4 register bit1. Pio mode and DMA mode can be select at Group119.4 register bit0.

Figure 22-9 shows the EMMC interrupt tree, figure 22-10 shows the SD/SDIO interrupt tree. The interrupt status can be read from registers. Please refer to register map chapter.
