GPIO Subsystem Register Descriptions
5.16.2.17 GPIO Input Positive Edge Status (GPIO[x]_IN_POSEDGE_STS)
These registers report the status of the positive edge detection function for the low (GPIO[15:0]) and high (GPIO[31:16])
banks of GPIOs. Writing a 1 clears the detected edge and reading returns the current status. (These registers use atomic
programming, see Section 5.16.1 on page 436 for details.)
