Chapter 3 Port Integration Module (PIM9NE64V1)
Read:Anytime.
Write:Anytime.
This register selects whether a pull-down or a pull-up device is connected to the pin.
PPSG[7:0] — Pull Select Port G
3.3.2.3.7
Read:Anytime.
Write:Anytime.
This register disables or enables on a per pin basis the edge sensitive external interrupt associated with port
G.
PIEG[7:0] — Interrupt Enable Port G
3.3.2.3.8
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 PPSG register. To clear this flag, write a “1” to the corresponding bit in the PIFG register.
Writing a “0” has no effect.
122
1 = Rising edge on the associated port G pin sets the associated flag bit in the PIFG register. A
0 = Falling edge on the associated port G pin sets the associated flag bit in the PIFG register. A
1 = Interrupt is enabled.
0 = Interrupt is disabled (interrupt flag masked).
