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  
bit 3  
bit 2  
Unimplemented: Read as ‘0’  
TMR0IP: TMR0 Overflow Interrupt Priority bit  
1= High priority  
0= Low priority  
bit 1  
bit 0  
Unimplemented: Read as ‘0’  
RBIP: RB Port Change Interrupt Priority bit  
1= High priority  
0= Low priority  
Note:  
Interrupt flag bits are set when an interrupt condition occurs, regardless of the state of its corresponding  
enable bit or the global enable bit. User software should ensure the appropriate interrupt flag bits are clear  
prior to enabling an interrupt. This feature allows for software polling.
