GPIO199-GPIO192

This register is EALLOW protected.

General-Purpose Input/Output (GPIO)

Select input qualification type for GPIO129

Qualification (3 samples)

Qualification (6 samples)

Async (no Sync or Qualification)

Select input qualification type for GPIO128

Qualification (3 samples)

Qualification (6 samples)

Async (no Sync or Qualification)

Any writes to these bit(s) must always have a value of 0.

Select input qualification type for GPIO128 to GPIO135 . The input qualification of each

GPIO input is controlled by two bits.

Synchronize to SYSCLKOUT only. Valid for both peripheral and GPIO pins.

Qualification using 3 samples. Valid for pins configured as GPIO or a peripheral function.

The time between samples is specified in the GPECTRL register.

Qualification using 6 samples. Valid for pins configured as GPIO or a peripheral function.

The time between samples is specified in the GPECTRL register.

Asynchronous. (no synchronization or qualification). This option applies to pins configured

as peripherals only. If the pin is configured as a GPIO input, then this option is the same as

0,0 or synchronize to SYSCLKOUT.
