C
Input
Serial control mode selection pin. “L” : 4-line serial, “H” : I2C bus
43
RX1
Input
Receiver channel input 1 pin. (Internal bias pin)
44
PDN
Input
Power down & reset pin.
When this pin is set to “L”, it falls into power down state; all the output pins change to “L”
and the register is initialized. If CAD1-0 is switched, reset it using the PDN pin.

Function
Figure 47 BLOCK DIAGRAM OF IC
Notes :
1. Grouping of the channels can be set with DZFM2-0 bit.
2. This pin turns to an OVF pin if the OVFE bit is set to “1”.
3. Except for the internal bias pins, any of the digital input pins must not be floated.
