bit 7

RBPU: PORTB Pull-up Enable bit

= All PORTB pull-ups are disabled

= PORTB pull-ups are enabled by individual port latch values

bit 6

INTEDG0: External Interrupt 0 Edge Select bit

= Interrupt on rising edge

= Interrupt on falling edge

bit 5

INTEDG1: External Interrupt 1 Edge Select bit

= Interrupt on rising edge

= Interrupt on falling edge

bit 4

INTEDG2: External Interrupt 2 Edge Select bit

= Interrupt on rising edge

= Interrupt on falling edge

bit 3

Unimplemented: Read as ‘0’

bit 2

TMR0IP: TMR0 Overflow Interrupt Priority bit

= High priority

= Low priority

bit 1

Unimplemented: Read as ‘0’

bit 0

RBIP: RB Port Change Interrupt Priority bit

= High priority

= Low priority

Legend:

R = Readable bit

W = Writable bit

U = Unimplemented bit, read as ‘0’

-n = Value at POR

‘1’ = Bit is set

‘0’ = Bit is cleared

x = Bit is unknown

Note:

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.
