Section 24 Power-Down Modes
24.4
24.4.1
Executing the SLEEP instruction when the STBY bit in STBCR1 is 0 causes a transition from the
program execution state to sleep mode. However, sleep mode cannot be entered when the bus is
released (low-level input to BREQ pin). 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.
24.4.2
Sleep mode is canceled by a reset.
Do not cancel sleep mode with an interrupt.
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.
