22.3
22.3.1
When the SLEEP instruction is executed while the SBYCR SSBY bit = 0 and the LPWRCR
LSON bit = 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 peripheral modules do not stop.
22.3.2
Sleep mode is exited by any interrupt, or signals at the RES, or STBY pins.
• Exiting Sleep Mode by Interrupts
• Exiting Sleep Mode by RES pin
• Exiting Sleep Mode by STBY Pin

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 pin level low selects the reset state. After the stipulated reset input duration,
driving the RES 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.
