REGISTER 9-6:
DS39609B-page 94
bit 7- 6
bit 5
bit 4
bit 3
bit 2-0
PIR3: PERIPHERAL INTERRUPT REQUEST (FLAG) REGISTER 3
Legend:
R = Readable bit
- n = Value at POR
bit 7
Unimplemented: Read as ‘0’
RC2IF: USART2 Receive Interrupt Flag bit
1 = The USART2 receive buffer, RCREG, is full (cleared when RCREG is read)
0 = The USART2 receive buffer is empty
TX2IF: USART2 Transmit Interrupt Flag bit
1 = The USART2 transmit buffer, TXREG, is empty (cleared when TXREG is written)
0 = The USART2 transmit buffer is full
TMR4IF: TMR3 Overflow Interrupt Flag bit
1 = TMR4 register overflowed (must be cleared in software)
0 = TMR4 register did not overflow
CCPxIF: CCPx Interrupt Flag bit (CCP Modules 3, 4 and 5)
Capture mode:
1 = A TMR1 or TMR3 register capture occurred (must be cleared in software)
0 = No TMR1 or TMR3 register capture occurred
Compare mode:
1 = A TMR1 or TMR3 register compare match occurred (must be cleared in software)
0 = No TMR1 or TMR3 register compare match occurred
PWM mode:
Unused in this mode.
