Figure 20.3 shows the timing for transition to and clearance of medium-speed mode.
Note: * Supported only by the H8S/2218 Group.
20.3
20.3.1
When the SLEEP instruction is executed when the SSBY bit in SBYCR and the LSON bit in
LPWRCR are cleared to 0, the CPU enters the sleep mode. In sleep mode, CPU operation stops
but the contents of the CPU's internal registers are retained. Other supporting modules do not stop.
20.3.2
Sleep mode is exited by any interrupt, or signals at the RES, MRES*, or STBY pin.
• Exiting Sleep Mode by Interrupts
• Exiting Sleep Mode by RES or MRES* Pin
• Exiting Sleep Mode by STBY Pin
Note: * Supported only by the H8S/2218 Group.

When an interrupt occurs, sleep mode is exited and interrupt exception processing starts. Sleep
mode is not exited if the interrupt is disabled, or interrupts other than NMI are masked by the
CPU.
Setting the RES or MRES* pin level Low selects the reset state. After the stipulated reset input
duration, driving the RES or MRES* pin High starts the CPU performing reset exception
processing.
When the STBY pin level is driven Low, a transition is made to hardware standby mode.
