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

23.0.5.62 Port AD0 Data Register 1 (PT1AD0)

Read: Anytime.

Write: Anytime.

Interrupt Flags Port J

0 No active edge pending. Writing a “0” has no effect.

1 Active edge on the associated bit has occurred (an interrupt will occur if the associated enable bit is set).

Writing a logic level “1” clears the associated ﬂag.
