 Function Setup for Serial I/O Pins
IOP and ION pins are set as 1 line CMOS I/O or 2-lane LVDS I/O with a SIG pin.

 Function of Transmission Status Error Indicator, FAULTN (Receiver mode)
FAULTN is the output pin. When the protocol of received data is not correct or serial data more than
50usec (typ) is not received, FAULTN pin will be changed into low level. The received data is
canceled when a FAULTN pin outputs Low. When normal serial data is received, a FAULTN pin
outputs High in case of pulled up externally.
 Digital Filter Function
When FILT pin is set to high level, the digital filter function is active. If the receiver matches the 3
sampling frequency content with the deserialized parallel data, it is updated as the correct data.
 Writing and Reading of Parallel Data by Serial Communication
The THCS134 is able to write and read data by 3-wire serial I/F on 16bit register.
