(c) Baud rate generator control register 0 (BRGC0)
BRGC0 is set by an 8-bit memory manipulation instruction.
RESET input sets BRGC0 to 00H.

Setting prohibited
—
Cautions 1. Writing to BRGC0 during a communication operation may cause abnormal output from
the baud rate generator and disable further communication operations. Therefore, do
not write to BRGC0 during a communication operation.
2. Set 10H to BRGC0 when using infrared data transfer mode.
