5.3.6 Direct Transition from
Subactive Mode to Active
(Medium-Speed) Mode
94 Added
When a SLEEP instruction is executed in subactive
mode while the SSBY and TMA3 bits in SYSCR1 are
set to 1, the LSON bit in SYSCR1 is cleared to 0, and
the MSON and DTON bits in SYSCR2 are set to 1, a
transition is made directly to active (medium-speed)
mode via watch mode after the waiting time set in bits
STS2 to STS0 in SYSCR1 has elapsed.
The time from the start of SLEEP instruction execution
to the end of interrupt exception handling (the direct
transition time) is calculated by equation (6).
Example: When φw/8 and φosc/8 are selected as the
CPU operating clock before and after the transition,
respectively, and wait time = 8192 states
Direct transition time = (2 + 1) × 8tw + 8192 × 1tosc +
14 × 8tosc = 24tw + 8304tosc

6.7 Notes on Setting Module
Standby Mode
… Then the flash memory should be set to enter the
module standby mode.
If an interrupt is generated in module standby mode,
the vector address cannot be fetched. As a result, the
program may run away.

Switching

for
CLKOUT output must be performed when
CLKOUT output is halted (CLKOUT = 0).
When making a transition to a power-down
mode wherein the system clock oscillator is
halted, the output level is retained. (In standby
mode, output is the high-impedance state.)
When making a transition from a power-down
mode wherein the system clock oscillator is
halted, to the active mode wherein the system
clock oscillator operates, halt CLKOUT output
(CLKOUT = 0) before the transition.
