Part III. Configuration
11.12.2 Low-Power Stop Operation
When the PowerPC core is set in a low-power mode (doze, sleep, deep sleep), the software
watchdog timer is frozen. It remains frozen and maintains its count value until the core exits
this mode and continues to execute instructions. The PIT, decrementer, and timebase are not
inßuenced by these low-power modes and they continue to run at their respective
frequencies. These timers can generate an interrupt to bring the MPC860 out of the
low-power modes.
