When the RES pin goes low, the CPU goes into the reset state and sleep mode is cleared.
6.2.2
In standby mode, the clock pulse generator stops, so the CPU and on-chip peripheral modules stop
functioning. However, as long as the rated voltage is supplied, the contents of CPU registers, on-
chip RAM, and some on-chip peripheral module registers are retained. On-chip RAM contents
will be retained as long as the voltage set by the RAM data retention voltage is provided. The I/O
ports go to the high-impedance state.
Standby mode is cleared by an interrupt. When an interrupt is requested, the system clock pulse
generator starts. After the time set in bits STS2 to STS0 in SYSCR1 has elapsed, and interrupt
exception handling starts. Standby mode is not cleared if the I bit of CCR is set to 1 or the
requested interrupt is disabled in the interrupt enable register.
When the RES pin goes low, the system clock pulse generator starts. Since system clock signals
are supplied to the entire chip as soon as the system clock pulse generator starts functioning, the
RES pin must be kept low until the pulse generator output stabilizes. After the pulse generator
output has stabilized, the CPU starts reset exception handling if the RES pin is driven high.
6.2.3
In subsleep mode, operation of the CPU and on-chip peripheral modules other than RTC is halted.
As long as a required voltage is applied, the contents of CPU registers, the on-chip RAM, and
some registers of the on-chip peripheral modules are retained. I/O ports keep the same states as
before the transition.
Subsleep mode is cleared by an interrupt. When an interrupt is requested, subsleep mode is cleared
and interrupt exception handling starts. Subsleep mode is not cleared if the I bit of CCR is set to 1
or the requested interrupt is disabled in the interrupt enable register. After subsleep mode is
cleared, a transition is made to active mode when the LSON bit in SYSCR2 is 0, and a transition is
made to subactive mode when the bit is 1. After the time set in bits STS2 to STS0 in SYSCR1 has
elapsed, a transition is made to active mode.
When the RES pin goes low, the system clock pulse generator starts. Since system clock signals
are supplied to the entire chip as soon as the system clock pulse generator starts functioning, the
RES pin must be kept low until the pulse generator output stabilizes. After the pulse generator
output has stabilized, the CPU starts reset exception handling if the RES pin is driven high.
