6.4.2
The time from the start of SLEEP instruction execution to the end of interrupt exception handling
(the direct transition time) is calculated by equation (2).
Direct transition time = {(number of SLEEP instruction execution states) + (number of internal
processing states)}
(number of interrupt exception handling states)}
6.5
The module-standby function can be set to any peripheral module. In module standby mode, the
clock supply to modules stops to enter the power-down mode. Module standby mode enables each
on-chip peripheral module to enter the standby state by setting a bit that corresponds to each
module to 1 and cancels the mode by clearing the bit to 0.
