(2) Generation of serial clock
386
A serial clock to be generated can be specified by using clock selection register 6 (CKSR6) and baud rate
generator control register 6 (BRGC6).
The clock to be input to the 8-bit counter can be set by bits 3 to 0 (TPS63 to TPS60) of CKSR6 and the division
value (f
