Chapter 23 DQ256 Port Integration Module (S12XDQ256PIMV2)
This register disables or enables on a per-pin basis the edge sensitive external interrupt associated with
Port J.
23.0.5.61 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.
23.0.5.62 Port AD0 Data Register 1 (PT1AD0)
Read: Anytime.
Write: Anytime.
