Description
CSTP1^*6
0
Peripheral clock is supplied to TMU channels 3 and 4
1
Peripheral clock supplied to TMU channels 3 and 4 is stopped
CSTP0^*6
0
INTC detects interrupts on TMU channels 3 and 4
1
INTC does not detect interrupts on TMU channels 3 and 4
MSTP6^*4
0
SQ operates
1
Clock supplied to SQ is stopped
MSTP5^*4
0
UBC operates
1
Clock supplied to UBC is stopped^*5
MSTP4
0
DMAC operates
1
Clock supplied to DMAC is stopped^*3
MSTP3
0
SCIF operates
1
Clock supplied to SCIF is stopped
MSTP2
0
TMU operates
1
Clock supplied to TMU is stopped, and register is initialized^*1
MSTP1
0
RTC operates
1
Clock supplied to RTC is stopped^*2
MSTP0
0
SCI operates
1
Clock supplied to SCI is stopped
Notes: 1. The register initialized is the same as in standby mode, but initialization is not
performed if the RTC clock is not in use (see section 12, Timer Unit (TMU)).
2. The counter operates when the START bit in RCR2 is 1 (see section 11, Realtime
Clock (RTC)).
3. Terminate DMA transfers prior to making the transition to module standby mode. If you
make a transition to module standby mode while DMA transfers are in progress, the
results of those transfers cannot be guaranteed.
4. SH7750S, SH7750R only
5. For details, see section 20.6, User Break Controller Stop Function.
6. SH7750R only
9.6.2 Exit from Module Standby Function
The module standby function is exited by clearing the MSTP6–MSTP0, CSTP1, and CSTP0 bits
to 0, or by a power-on reset via the RESET pin or a power-on reset caused by watchdog timer
overflow.
