Section 19 Power-Down Modes
19.4 Sleep Mode
19.4.1 Transition to Sleep Mode
Executing the SLEEP instruction when the STBY bit in STBCR1 is 0 causes a transition from the
program execution state to sleep mode. Although the CPU halts immediately after executing the
SLEEP instruction, the contents of its internal registers remain unchanged. The on-chip peripheral
modules continue to operate.
19.4.2 Canceling Sleep Mode
Sleep mode is canceled by a reset.
(1) Canceling with Reset
Sleep mode is canceled by a power-on reset with the RES pin, a manual reset with the MRES pin,
or an internal power-on/manual reset by WDT. Do not cancel sleep mode with an interrupt.
