a. Keeper column: N = pad has no keeper. Y = pad has a keeper. Keeper is always active except in Power-down state. If there is no keeper, and it is an input
and there is Nopull, then the pad should be driven to prevent leakage due to floating pad (SDIO_CLK, for example).
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, it can be either output or input.
d. Depending on whether the I²S interface is enabled and the configuration of I²S is in master or slave mode, it can be either output or input
e. NoPull when in SDIO mode.
