Value
Select input qualification type for GPIO32 to GPIO47 . The input qualification of each GPIO
input is controlled by two bits.
00 Synchronize to SYSCLKOUT only. Valid for both peripheral and GPIO pins.
01 Qualification using 3 samples. Valid for pins configured as GPIO or a peripheral function.
The time between samples is specified in the GPBCTRL register.
10 Qualification using 6 samples. Valid for pins configured as GPIO or a peripheral function.
The time between samples is specified in the GPBCTRL register.
11 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.
