Bits 1 and 0—Clock Enable 1 and 0 (CKE1, CKE0)
Bits 1 and 0 select the clock source and enabling or disabling of clock output from the SCK
The combination of CKE1 and CKE0 determines whether the SCK
a clock output pin, or a clock input pin.
The CKE0 bit setting is only valid in case of internal clock operation (CKE1 = 0) in asynchronous
mode. In synchronous mode, or when external clock operation is used (CKE1 = 1), bit CKE0
should be cleared to 0.
After setting bits CKE1 and CKE0, set the operating mode in the serial mode register (SMR).
For details on clock source selection, see table 10.9.

Notes: 1. Initial value
2. A clock with the same frequency as the bit rate is output.
3. Input a clock with a frequency 16 times the bit rate.
