Section 24 Power-Down State
Bit 7—Software Standby (SSBY): Determines the operating mode, in combination with other
control bits, when a power-down mode transition is made by executing a SLEEP instruction. The
SSBY setting is not changed by a mode transition due to an interrupt, etc.

Bits 6 to 4—Standby Timer Select 2 to 0 (STS2 to STS0): These bits select the time the MCU
waits for the clock to stabilize when software standby mode, watch mode, or subactive mode is
cleared and a transition is made to high-speed mode or medium-speed mode by means of a
specific interrupt or instruction. With crystal oscillation, refer to table 24.5 and make a selection
according to the operating frequency so that the standby time is at least 8 ms (the oscillation
settling time). With an external clock, any selection can be made.

Note:
Bit 3—Reserved: This bit cannot be modified and is always read as 0.
