Bits 2 to 0—System clock select (SCK2 to SCK0): These bits select the bus master clock in
high-speed mode, medium-speed mode, and sub-active mode.
Set SCK2 to SCK0 all to 0 when shifting to operation in watch mode or sub-active mode.

21B.2.3 Low-Power Control Register (LPWRCR)
The LPWRCR is an 8-bit read/write register that controls the low power dissipation modes.
The LPWRCR is initialized to H'00 at a reset and when in hardware standby mode. It is not
initialized in software standby mode. The following describes bits 7 to 2. For details of other bits,
see section 20.2.2, Low-Power Control Register (LPWRCR).
