Description
This field selects the GPIO pin or internal global signal to be
monitored. Refer to
Timestamping event mode:
Description
This field indicates the direction of the event which occurred:
This field holds the 31-bit timestamp.
Description
GPIO master time counter. This counter is incremented at a
frequency of 13.5 MHz.
00 - event detection disabled
01 - capture negative edge
10 - capture positive edge
11 - capture either edge
0 - a falling edge
1 - a rising edge
