PIR1 REGISTER
This register contains the individual ag bits for the
Peripheral interrupts.
FIGURE 2-7:
PIR1 REGISTER (ADDRESS 0Ch)
Note:
Interrupt ag bits get set when an interrupt
condition occurs regardless of the state of
its corresponding enable bit or the global
enable bit, GIE (INTCON<7>). User soft-
ware should ensure the appropriate inter-
rupt ag bits are clear prior to enabling an
interrupt.

bit 7:
Unimplemented: Read as '0'
bit 6:
ADIF: A/D Converter Interrupt Flag bit
1 = An A/D conversion completed (must be cleared in software)
0 = The A/D conversion is not complete
bit 5-4: Unimplemented: Read as '0'
bit 3:
SSPIF: Synchronous Serial Port Interrupt Flag bit
1 = The transmission/reception is complete (must be cleared in software)
0 = Waiting to transmit/receive
bit 2:
CCP1IF: CCP1 Interrupt Flag bit
Capture Mode
1 = A TMR1 register capture occurred (must be cleared in software)
0 = No TMR1 register capture occurred
Compare Mode
1 = A TMR1 register compare match occurred (must be cleared in software)
0 = No TMR1 register compare match occurred
PWM Mode
Unused in this mode
bit 1:
TMR2IF: TMR2 to PR2 Match Interrupt Flag bit
1 = TMR2 to PR2 match occurred (must be cleared in software)
0 = No TMR2 to PR2 match occurred
bit 0:
TMR1IF: TMR1 Overow Interrupt Flag bit
1 = TMR1 register overowed (must be cleared in software)
0 = TMR1 register did not overow
