22.6.4
Figure 22.4 shows the timing sequence at power-on.
At power-on, the RES pin must be driven low with the STBY pin driven high for a given time in
order to clear the reset state.
To enter hardware standby mode immediately after power-on, drive the STBY pin low after
exiting the reset state.
For details on clearing hardware standby mode, see section 22.6.3, Hardware Standby Mode
Timing.
22.7
22.7.1
Module stop mode can be set for individual on-chip peripheral modules.
When the corresponding MSTP bit in MSTPCRA, MSTPCRB, or MSTPCRC is set to 1, module
operation stops at the end of the bus cycle and a transition is made to module stop mode. The CPU
continues operating independently.
When the corresponding MSTP bit is cleared to 0, module stop mode is cleared and the module
starts operating at the end of the bus cycle. In module stop mode, the internal states of modules
other than the SCI are retained.
