Address 0x0260

Write: Anytime.

Port P interrupt ﬂag—

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 PPSP register. To clear this ﬂag, write logic level 1 to the corresponding bit in the PIFP register. 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).

0 No active edge pending.
