2.3.3 INTCON REGISTER

The INTCON Register is a readable and writable regis-

ter which contains various enable and flag bits for the

TMR0 register overflow, RB Port change and external

RB0/INT pin interrupts.

PIC16C925/926

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, GIE (INTCON<7>).

bit 7

GIE: Global Interrupt Enable bit

1 = Enables all unmasked interrupts

0 = Disables all interrupts

bit 6

PEIE/GEIL: Peripheral Interrupt Enable bit

1 = Enables all unmasked peripheral interrupts

0 = Disables all peripheral interrupts

bit 5

TMR0IE: TMR0 Overflow Interrupt Enable bit

1 = Enables the TMR0 overflow interrupt

0 = Disables the TMR0 overflow interrupt

bit 4

INTE: RB0/INT0 External Interrupt Enable bit

1 = Enables the RB0/INT external interrupt

0 = Disables the RB0/INT external interrupt

bit 3

RBIE: RB Port Change Interrupt Enable bit

1 = Enables the RB port change interrupt

0 = Disables the RB port change interrupt

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

INTF: RB0/INT0 External Interrupt Flag bit

1 = The RB0/INT external interrupt occurred (must be cleared in software)

0 = The RB0/INT external interrupt did not occur

bit 0

RBIF: RB Port Change Interrupt Flag bit

1 = At least one of the RB7:RB4 pins changed state (must be cleared in software)

0 = None of the RB7:RB4 pins have changed state

Legend:

R = Readable bit

- n = Value at POR reset

W = Writable bit

’1’ = Bit is set

U = Unimplemented bit, read as ‘0’

’0’ = Bit is cleared x = Bit is unknown
