Manufacturer Part Number
upd78f0103hmca1-5a4-a
Description
8-bit Single-chip Microcontrollers
Manufacturer
Renesas Electronics Corporation.
Datasheet
(5) Baud rate generator control register 6 (BRGC6)
Address: FF57H 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 input 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 value is the output clock of the 8-bit counter divided by 2.
