(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.

(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 indicate an SD Card/Memory device is present.
