Section 23 Clock Pulse Generator
23.1.2
The clock pulse generator is controlled by the standby control register (SBYCR) and low-power
control register (LPWRCR). Table 23.1 shows the register configuration.

23.2.1
SBYCR is an 8-bit readable/writable register that performs power-down mode control.
Only bits 0 to 2 are described here. For a description of the other bits, see section 24.2.1, Standby
Control Register (SBYCR).
SBYCR is initialized to H'00 by a reset and in hardware standby mode. It is not initialized in
software standby mode.
Bits 2 to 0—System Clock Select 2 to 0 (SCK2 to SCK0): These bits select the bus master clock
for high-speed mode and medium-speed mode.
When operating the device after a transition to subactive mode or watch mode bits SCK2 to SCK0
should all be cleared to 0.
