Description
Software must not rely on the value of a reserved. Writing any other
value than the reset value may result in undefined behavior.
Controls latches between MCU IOC and AON_IOC.
The latches are transparent by default.
They must be closed prior to power off the domain(s) controlling the
IOs in order to preserve IO values on external pins.
0h = Latches are static, meaning the current value on the IO pin is
frozen by latches and kept even if GPIO module or a peripheral
module is turned off
1h = Latches are transparent, meaning the value of the IO is directly
controlled by the GPIO or peripheral value
