24.0.5.57 Port J Interrupt Flag Register (PIFJ)
Read: Anytime.
Write: Anytime.
Each flag is set by an active edge on the associated input pin. This could be a rising or a falling edge based
on the state of the PPSJ register. To clear this flag, write logic level “1” to the corresponding bit in the PIFJ
register. Writing a “0” has no effect.
24.0.5.58 Port AD1 Data Register 0 (PT0AD1)
Read: Anytime.
Write: Anytime.
This register is associated with AD1 pins PAD[15:8]. These pins can also be used as general purpose I/O.
