(4) Clock selection register 6 (CKSR6)
Address: FF96H After reset: 00H R/W
Caution Make sure POWER6 = 0 when rewriting TPS63 to TPS60.
Remarks 1. Figures in parentheses are for operation with f
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 clears this register to 00H.
Remark CKSR6 can be refreshed (the same value is written) by software during a communication operation
2. f
(when bit 7 (POWER6) and bit 6 (TXE6) of ASIM6 = 1 or bit 7 (POWER6) and bit 5 (RXE6) of ASIM6
= 1).
