4. The clock pulse generator stops, and the setting for the STC1 and STC0 bits becomes valid.
5. Software standby mode or watch mode is exited, and the transition time set by the STS2 to
6. After the set transition time is elapsed, this LSI resumes operation with the changed
When the STCS bit is set to 1, after rewriting the STC1 and STC0 bits, this LSI operates with the
changed multiplication ratio.
21.4
The medium-speed clock divider divides the system clock to generate φ/2, φ/4, φ/8, φ/16, and
φ/32.
21.5
The bus master clock selection circuit selects the clock supplied to the bus master by setting the
SCK2 to SCK0 bits in SCKCR. The bus master clock can be selected from system clock (φ), or
medium-speed clocks (φ/2, φ/4, φ/8, φ/16, and φ/32).
