The PIC16F193X/LF193X device family features an
interruptible core, allowing certain events to preempt
normal program flow. An Interrupt Service Routine
(ISR) is used to determine the source of the interrupt
and act accordingly. Some interrupts can be configured
to wake the MCU from Sleep mode.
The PIC16F193X/LF193X device family has 23 inter-
rupt sources, differentiated by corresponding interrupt
enable and flag bits:
• External Edge Detect on INT Pin Interrupt
• Interrupt-on-Change Interrupt
• A/D Conversion Complete Interrupt
• EEPROM Write Complete Interrupt
• EUSART Receive Interrupt
• EUSART Transmit Interrupt
• LCD Module Interrupt
• Oscillator Fail Interrupt
