Read and write anytime.
Each flag is set by an active edge on its associated input pin. This could
be a rising or falling edge based on the state of the KWPJ register. To
clear the flag, write one to the corresponding bit in KWIFJ.
Initialize this register after initializing KWPJ so that illegal flags can be
cleared.
KWIFJ[7:0] — Key Wake-up Port J Flags
Read and write anytime.
Each flag is set by an active edge on its associated input pin. This could
be a rising or falling edge based on the state of the KWPH register. To
clear the flag, write one to the corresponding bit in KWIFH.
Initialize this register after initializing KWPH so that illegal flags can be
cleared.
