This register is used to indicate configuration for the GPIO signal that is selected in the GPIO Signal Configuration Select Register
(above).

PME debouncing, polarity, and edge/level configuration is only applicable on GPIO0-GPIO15 signals (Bank 0 = 00000 to
01111) and on GPIO32-GPIO47 signals (Bank 1 settings of 00000 to 01111). The remaining GPIOs (GPIO16-GPIO31 and
GPIO48-GPIO63) can not generate PMEs, therefore these bits have no function and read 0.
Description
Signal Select. Selects the GPIO signal to be configured in the Bank selected via bit 5 setting (i.e., Bank 0 or Bank 1). See
Table 4-2 on page 88 for GPIO ball muxing options. GPIOs without an associated ball number are not available externally.

Note:
Reserved. Must be set to 0.
PME Debounce Enable. Enables/disables IRQ debounce (debounce period = 16 ms).
0: Disable.
1: Enable. (Default).
See the note in the description of this register for more information about the default value of this bit.
PME Polarity. Selects the polarity of the signal that issues a PME from the selected GPIO signal (falling/low or rising/high).
0: Falling edge or low level input. (Default)
1: Rising edge or high level input.
See the note in the description of this register for more information about the default value of this bit.
