PIR2 REGISTER

The PIR2 register contains the interrupt flag bits, as

shown in Register 4-6.

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 of the INTCON register.

User

software

should

ensure

the

appropriate interrupt flag bits are clear prior

to enabling an interrupt.

Legend:

R = Readable bit

W = Writable bit

U = Unimplemented bit, read as ‘0’

u = bit is unchanged

x = Bit is unknown

-n/n = Value at POR and BOR/Value at all other Resets

‘1’ = Bit is set

‘0’ = Bit is cleared

bit 7

OSFIF: Oscillator Fail Interrupt Flag

= System oscillator failed, clock input has changed to INTOSC (must be cleared in software)

= No oscillator failure has been detected

bit 6

C2IF: Comparator C2 Interrupt Flag

= An enabled edge was detected on Comparator C2 (must be cleared in software)

= No enabled edge was detected on Comparator C2

bit 5

C1IF: Comparator C1 Interrupt Flag

= An enabled edge was detected on Comparator C1 (must be cleared in software)

= No enabled edge was detected on Comparator C1

bit 4

EEIF: EEPROM Write Completion Interrupt Flag bit

= The EEPROM Write operation has completed (must be cleared in software)

= The EEPROM Write operation has not completed or has not been started

bit 3

BCLIF: MSSP Bus Collision Interrupt Flag bit

= A Bus Collision was detected (must be cleared in software)

= No Bus collision was detected

bit 2

LCDIF: LCD Module Interrupt Flag bit

= The LCD module has completed displaying a frame (must be cleared in software).

= The LCD module has not completed displaying a frame

bit 1

Unimplemented: Read as ‘0’

bit 0

CCP2IF: CCP2 Interrupt Flag bit

Capture Mode

A TMR1 register capture occurred (must be cleared in software)

No TMR1 register capture occurred

Compare Mode

A TMR1 register compare match occurred (must be cleared in software)

No TMR1 register compare match occurred

PWM Mode

Unused in this mode
