Section 28 Power-Down Mode
28.6 Module Standby Mode
28.6.1 Transition to Module Standby Mode
Setting the bits in the module stop register to 1 halts the clock supply to the corresponding on-chip
peripheral modules.
Modules in module standby mode keep the state immediately before the transition to the module
standby mode. The registers retain their contents before the module is halted, and the external pins
also hold their states before halted. At waking up from the module standby state, operation starts
from the condition immediately before the module was halted.
28.6.2 Canceling Module Standby Mode
The module standby mode can be canceled by clearing the respective bit in the module stop
register to 0 or by a power-on reset.
