Section 21B Power-Down Modes [H8S/2626 Group]
Bit 7—Software Standby (SSBY): When making a low power dissipation mode transition by
executing the SLEEP instruction, the operating mode is determined in combination with other
control bits.
Note that the value of the SSBY bit does not change even when shifting between modes using
interrupts.

Bits 6 to 4—Standby Timer Select 2 to 0 (STS2 to STS0): These bits select the MCU wait time
for clock stabilization when shifting to high-speed mode or medium-speed mode by using a
specific interrupt or command to cancel software standby mode, watch mode, or sub-active mode.
With a quartz oscillator (table 21B.5), select a wait time of 8ms (oscillation stabilization time) or
more, depending on the operating frequency. With an external clock, there are no specific wait
requirements.

Description
Shifts to sleep mode when the SLEEP instruction is executed in high-speed
mode or medium-speed mode.
Shifts to sub-sleep mode when the SLEEP instruction is executed in
sub-active mode.
Shifts to software standby mode, sub-active mode, and watch mode when the SLEEP
instruction is executed in high-speed mode or medium-speed mode.
Shifts to watch mode or high-speed mode when the SLEEP instruction is executed in
sub-active mode.
