(5) Baud rate generator control register 6 (BRGC6)
Address: FF97H After reset: FFH R/W
BRGC6
Cautions 1. Make sure that bit 6 (TXE6) and bit 5 (RXE6) of the ASIM6 register = 0 when rewriting the
Remarks 1. f
Symbol
This register sets the division value of the 8-bit counter of serial interface UART6.
BRGC6 can be set by an 8-bit memory manipulation instruction.
Reset signal generation sets this register to FFH.
Remark BRGC6 can be refreshed (the same value is written) by software during a communication operation
2. The baud rate is the output clock of the 8-bit counter divided by 2.
2. k: Value set by MDL67 to MDL60 bits (k = 8, 9, 10, ..., 255)
3. ×: Don’t care
MDL67
MDL67
(when bit 7 (POWER6) and bit 6 (TXE6) of ASIM6 = 1 or bit 7 (POWER6) and bit 5 (RXE6) of ASIM6
= 1).
