GPIO0P2_BATIDOUT:

Battery ID output to SoC for digital battery communication. Optional function multiplexed with low voltage

GPIO0P2

GPIO0P[7:3]:

Low voltage GPIOs with no alternate functions

9.1.33.2

High Voltage GPIOs

GPIO1P0_UIBTN_B:

The UIBTN_B pin is an input from a platform-defined functional interface button, such as the Home button. It

includes a 30ms de-

bouncer to ensure that spurious transitions aren‘t logged while the switch contacts bounce

on initial contact. The output of the de-bouncer enters the edge detect circuits.

GPIO1P[7:1]:

High voltage GPIOs with no alternate functions
