Low-Power Modes
The STOP and WAIT instructions put the MCU in low-power
consumption standby modes.
Stop Mode
The STOP instruction suspends the timer counter. Upon exit from stop
mode by external reset:
• The timer counter resumes counting from $FFFC.
• An input capture edge during stop mode does not affect the ICF
bit or the input capture registers.
Upon exit from stop mode by external interrupt:
• The counter resumes counting from the suspended value.
• An input capture edge during stop mode sets the ICF bit and
transfers the suspended timer counter value to the input capture
registers.
Wait Mode
The timer remains active after a WAIT instruction. Any enabled timer
interrupt request can bring the MCU out of wait mode.
