Section 24 Power-Down State
24.9
24.9.1
If a SLEEP instruction is executed in subactive mode when the SSBY in SBYCR is cleared to 0,
the LSON bit in LPWRCR is set to 1, and the PSS bit in TCSR (WDT1) is set to 1, the CPU
makes a transition to subsleep mode.
In this mode, the CPU and all on-chip supporting modules except TMR0, TMR1, WDT0, and
WDT1 stop. As long as the prescribed voltage is supplied, the contents of some of the CPU’s
internal registers and on-chip RAM are retained, and I/O ports retain their states prior to the
transition.
24.9.2
Subsleep mode is cleared by an interrupt (on-chip supporting module interrupt, NMI pin, or pin
IRQ0 to IRQ7), or by means of the RES pin or STBY pin.
Clearing with an Interrupt: When an interrupt request signal is input, subsleep mode is cleared
and interrupt exception handling is started. Subsleep mode cannot be cleared with an IRQ0 to
IRQ7 interrupt if the corresponding enable bit has been cleared to 0, or with an on-chip supporting
module interrupt if acceptance of the relevant interrupt has been disabled by the interrupt enable
register or masked by the CPU.
