(4) Clock selection register 6 (CKSR6)
346
Address: FF56H After reset: 00H R/W
Remark CKSR6 can be refreshed (the same value is written) by software during a communication operation
Notes 1.
Caution Make sure POWER6 = 0 when rewriting TPS63 to TPS60.
Remark
Symbol
CKSR6
This register selects the base clock of serial interface UART6.
CKSR6 can be set by an 8-bit memory manipulation instruction.
Reset signal generation sets this register to 00H.
