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 in infrared data transfer mode.
