Address: FF71H After reset: 1FH R/W
BRGC0
Notes 1.
Cautions 1. Make sure that bit 6 (TXE0) and bit 5 (RXE0) of the ASIM0 register = 0 when rewriting the
Symbol
This register selects the base clock of serial interface UART0 and the division value of the 5-bit counter.
BRGC0 can be set by an 8-bit memory manipulation instruction.
Reset signal generation sets this register to 1FH.
2.
2. The baud rate value is the output clock of the 5-bit counter divided by 2.
If the peripheral hardware clock (f

When selecting the TM50 output as the base clock, Start the operation of 8-bit timer/event counter 50
first and then enable the timer F/F inversion operation (TMC501 = 1).
