12.10.10 PIR3
Note:
- RC2IF is read-only. User software must read RC2REG to clear RC2IF.
- TX2IF is read-only. User software must load TX2REG to clear TX2IF. TX2IF does not indicate a completed transmission (use TMRT for this purpose instead).
- RC1IF is read-only. User software must read RC1REG to clear RC1IF.
- TX1IF is read-only. User software must load TX1REG to clear TX1IF. TX1IF does not indicate a completed transmission (use TMRT for this purpose instead).
- Interrupt flag bits are set when an Interrupt condition occurs, regardless of the state of its corresponding enable bit or the Global Enable (GIE) bit. User software may ensure the appropriate interrupt flag bits are cleared before enabling an interrupt.
