27.1.7 Interrupts

The SMT has three interrupts located in one of the PIR registers:
  • Pulse-Width Acquisition Interrupt (SMTxPWAIF): Interrupt triggers when the SMTxCPW register is updated with the SMTxTMR register value.
  • Period Acquisition Interrupt (SMTxPRAIF): Interrupt triggers when the SMTxCPR register is updated with the SMTxTMR register value.
  • Counter Period Match Interrupt (SMTxIF): Interrupt triggers when the SMTxTMR register equals the SMTxPR register.

Each of the above interrupts can be enabled/disabled using the corresponding bits in the PIE register.
