: Enables to start oscillator warm-up timer.
: Indicates status of warm-up timer for oscillator.
: Selects PLL （multiplying circuit） operation.
: Selects oscillator to warm-up.
: Selects oscillator warm-up time.
: Selects high-speed oscillator operation.
: Selects low-speed oscillator operation.
: Selects current for high-speed oscillator.
: Selects current for low-speed oscillator.
The <DRVOSCH> bit is cleared to “0” (large current) when the mode is shifted
from STOP to normal even if the bit is set to ”1” (small current) in shifting to STOP
mode.
Reconfigure the bit if needed.
The <DRVOSCL> bit is cleared to “0” (large current) when the mode is shifted
from STOP to normal even if the bit is set to ”1” (small current) in shifting to STOP
mode.
Reconfigure the bit if needed.
It stops after reset. Reconfiguration is required.
