a. N = Pad has no keeper; Y = Pad has a keeper. The keeper is always active except in power down state.
If there is no keeper, it is an input, and there is no pull, then the pad should be driven to prevent leakage due to the floating pad (e.g., SDIO_CLK).
b. In the power down state (xx_REG_ON = 0), High-Z; noPull: the pad is disabled because power is not supplied.
c. Depending on whether the PCM interface is enabled and the configuration of PCM is in master or slave mode, this can be either output or input.
2
d. The I S interface is shared with GPIO2, 3, 4, and 5. Up to master or slave mode, it can be either output or input.
