88 / 251 page  Table 6-102. MMC0 Signal Descriptions (continued) SIGNAL NAME PIN TYPE DESCRIPTION ALZ PIN MMC0_DAT7(2) IO MMC/SD/SDIO Data AG1 (1) An external 10 kΩ ±1% resistor must be connected between this pin and VSS. No external voltage should be applied to this pin. (2) An external pull-up of 10 kΩ ~ 50 kΩ ±1% resistor, as specified in the specification, must be connected to this ball to ensure proper operation.

MMC1 Signal Descriptions SIGNAL NAME PIN TYPE DESCRIPTION ALZ PIN MMC1_CLK(1) IO MMC/SD/SDIO Clock P23 MMC1_CMD IO MMC/SD/SDIO Command N24 MMC1_SDCD(2) I SD Card Detect AE25 MMC1_SDWP I SD Write Protect AG25 MMC1_DAT0 IO MMC/SD/SDIO Data M23 MMC1_DAT1 IO MMC/SD/SDIO Data P24 MMC1_DAT2 IO MMC/SD/SDIO Data R24 MMC1_DAT3 IO MMC/SD/SDIO Data R22 (1) For MMC1_CLK signal to work properly, the RXACTIVE bit of the CTRLMMR_PADCONFIG171 register should be set to 0x1 because of retiming purposes. (2) For ROM boot from MMC1 interface to work properly, the MMC1_SDCD pin should be pulled low externally with a resistor to indicated an SD Card/Memory device is present. 6.3.27 OSPI 6.3.27.1 MCU Domain Table 6-104.
