6.3 Stop Mode
The STOP instruction places the MCU in its lowest-power consumption
mode. In stop mode, the internal oscillator is turned off, halting all
internal processing, including timer operation.
During stop mode, the TCR bits are altered to remove any pending timer
interrupt request and to disable any further timer interrupts. The timer
prescaler is cleared. The I bit in the condition code register is cleared to
enable external interrupts. All other registers and memory remain
