Description
On-Chip Oscillator Standby
The on-chip oscillator standby state is entered by setting
this bit to 1.
Frequency Select for On-chip Oscillator
0: 16 MHz
1: 20 MHz
Power Supply Select for On-chip Oscillator
0: Selects VBGR
1: Selects VCL
When the VCL power is selected, the accuracy of the on-
chip oscillator frequency cannot be guaranteed.
Reserved
These bits are always read as 0.
Division Ratio Select for On-chip Oscillator
The division ratio of
bit.
These bits can be written to only when the CKSTA bit in
CKCSR is 0.
