Section 25 Power-Down State
25.4
25.4.1
If a SLEEP instruction is executed when the SSBY bit in SBYCR and the LSON bit in LPWRCR
are both cleared to 0, the CPU enters 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.
25.4.2
Sleep mode is cleared by any interrupt, or with the RES pin or STBY pin.
Clearing with an Interrupt: When an interrupt request signal is input, sleep mode is cleared and
interrupt exception handling is started. Sleep mode will not be cleared if interrupts are disabled, or
if interrupts other than NMI have been masked by the CPU.
Clearing with the RES
RES pin is driven high after the prescribed reset input period, the CPU begins reset exception
handling.
Clearing with the STBY
standby mode.
