Section 6 Power-Down Modes
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)} × (tsubcyc before transition) +
{(waiting time set in bits STS2 to STS0) + (number of interrupt exception handling states)} ×
(tcyc after transition)…………………………………………………………………………(2)
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.
