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.
Remarks 1. f
: Source clock for 5-bit counter
SCK
Value set via TPS00 to TPS02 (0 ≤ n ≤ 7)
