Section 17 Power-Down Mode
17.4
17.4.1
A transition to the sleep mode is made by executing the SLEEP instruction in the program
execution state. Although the CPU stops operating after execution of the SLEEP instruction, the
contents of the CPU registers are held.
On-chip peripheral modules other than the CPU continue to operate and the clock continues to be
output on the CLKOUT pin.
In sleep mode, a high-level signal is output at the STATUS1 pin, and a low-level signal at the
STATUS0 pin.
17.4.2
The sleep mode is canceled by an interrupt (NMI, IRQ/IRL[7:0], or on-chip modules) and a reset.
Since an interrupt is accepted in sleep mode even if the BL bit in SR is set to 1, save the contents
of SPC and SSR to the stack before executing the SLEEP instruction when necessary.
Cancellation by Interrupt: The sleep mode can be canceled with an NMI, IRQ/IRL[7:0], or on-
chip module interrupt, and the interrupt exception handling then starts. A corresponding code to
the interrupt is stored in INTVENT.
Cancellation by Reset: The sleep mode is canceled with a power-on reset by the PRESET pin, a
power-on reset by a watchdog timer overflow, or a manual reset.
