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

ADIF: A/D Converter Interrupt Flag bit

1 = A/D conversion complete (must be cleared by software)

0 = A/D conversion has not completed or has not been started

bit 6

CWIF: Comparator 1 or 2 Interrupt Flag bit

1 = Comparator interrupt-on-change has occurred(1)

0 = No change in Comparator 1 or 2 output

bit 5

T0IF: Timer0 Overflow Interrupt Flag bit

1 = TMR0 register has overflowed (must be cleared by software)

0 = TMR0 register did not overflow

bit 4

RBIF: PORTB Interrupt-on-change Flag bit

1 = Wake-up or interrupt has occurred (cleared in software)(2)

0 = Wake-up or interrupt has not occurred

bit 3-1

Unimplemented: Read as ‘0’

bit 0

GIE: Global Interrupt Enable bit

1 = Interrupt sets PC to address 0x004 (Vector to ISR)

0 = Interrupt causes wake-up and inline code execution

Note 1: This bit only functions when the C1WU or C2WU bits are set (see Register 10-1 and Register 10-2).

2: The RBWU bit of the OPTION register must be set to enable this function (see Register 4-2).
