26.2 Registers
The CEC function's bits and registers are synchronized with the count source. Register values change
immediately after being rewritten by a program, while the internal circuit starts operating from the next
count source timing.

CECEN (CEC enable bit) (b0)
Set the CECEN bit to 1 (enabled) when the count source is selected by using bits CCLK1 to CCLK0
and the count source is stable.
When the CECEN bit is set to 0 (disabled), the circuit of the CEC function is reset.
CCLK1 to CCLK0 (Clock source select bit) (b2-b1)
Change the clock source when the CECEN bit is set 0 (CEC disabled).
