„ Bi-phase Input
Six receiver inputs (RX1-6) are available in serial control mode. IPS2-0 bits select the receiver channel. In parallel
control mode, two receiver inputs (RX1 or RX5) are available. The receiver channel is selected by IPS pin. Each input
includes an amplifier for unbalanced mode that can accept a signal of 350mV or more. When BCU and UCE bits are
changed, the Block start signal, C bit and U bit can output from each pins. (See Table 12 and Figure 16)
