INTCON Registers
The INTCON registers are readable and writable
registers which contain various enable, priority and flag
bits.
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.
REGISTER 10-1:
INTCON: INTERRUPT CONTROL REGISTER
R/W-0
R/W-x
GIE/GIEH
PEIE/GIEL
TMR0IE
INT0IE
RBIE
TMR0IF
INT0IF
RBIF
bit 7
bit 0
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
bit 7
GIE/GIEH:
Global Interrupt Enable bit
When IPEN = 0:
1
= Enables all unmasked interrupts
0
= Disables all interrupts
When IPEN = 1:
1
= Enables all high-priority interrupts
0
= Disables all high-priority interrupts
bit 6
PEIE/GIEL:
Peripheral Interrupt Enable bit
When IPEN = 0:
1
= Enables all unmasked peripheral interrupts
0
= Disables all peripheral interrupts
When IPEN = 1:
1
= Enables all low-priority peripheral interrupts
0
= Disables all low-priority peripheral interrupts
bit 5
TMR0IE:
TMR0 Overflow Interrupt Enable bit
1
= Enables the TMR0 overflow interrupt
0
= Disables the TMR0 overflow interrupt
bit 4
INT0IE:
INT0 External Interrupt Enable bit
1
= Enables the INT0 external interrupt
0
= Disables the INT0 external interrupt
bit 3
RBIE:
RB Port Change Interrupt Enable bit
1
= Enables the RB port change interrupt for RB<7:4> pins
0
= Disables the RB port change interrupt for RB<7:4> pins
bit 2
TMR0IF:
TMR0 Overflow Interrupt Flag bit
1
= TMR0 register has overflowed (must be cleared in software)
0
= TMR0 register did not overflow
bit 1
INT0IF:
INT0 External Interrupt Flag bit
1
= The INT0 external interrupt occurred (must be cleared in software)
0
= The INT0 external interrupt did not occur
bit 0
RBIF:
RB Port Change Interrupt Flag bit
1
= At least one of the RB<7:4> pins changed state (must be cleared in software)
0
= None of the RB<7:4> pins have changed state
