RBPU
Interrupt flag bits are set when an interrupt condition occurs regardless of the state of its corresponding
enable bit or the global interrupt enable bit. User software should ensure the appropriate interrupt flag bits
are clear prior to enabling an interrupt. This feature allows for software polling.
RBPU: PORTB Pull-up Enable bit
1 = All PORTB pull-ups are disabled
0 = PORTB pull-ups are enabled by individual port latch values
INTEDG0: External Interrupt 0 Edge Select bit
1 = Interrupt on rising edge
0 = Interrupt on falling edge
INTEDG1: External Interrupt 1 Edge Select bit
1 = Interrupt on rising edge
0 = Interrupt on falling edge
INTEDG2: External Interrupt 2 Edge Select bit
1 = Interrupt on rising edge
0 = Interrupt on falling edge
Unimplemented: Read as ‘0’
TMR0IP: TMR0 Overflow Interrupt Priority bit
1 = High priority
0 = Low priority
Unimplemented: Read as ‘0’
RBIP: RB Port Change Interrupt Priority bit
1 = High priority
0 = Low priority
