Accordingly, the transfer rate of the receiver and transmitter sides must satisfy the following fomula in
order to receive data correctly.

1 _xb
Bt
Br : Transfer rate on receiver side (bps)
Bt : Transfer rate on transmitter side (bps)
F : BRGi's count source frequency on receiver side (Hz)
b : Entire bit number of one-set data
(ex : 12 bits in the case of 1ST-8DATA-1PAR-2SP; See Figure 2.5.1)
Be sure to satisfy the above formula, and set the timing with enough margin. Also, the user shall make
sufficient evaluation before actually using it.
