Data Channel TMDS input termination resistor RT, Rpd Control
Pull-down resistor Rpd active conditions:
1. The Data Channel RT is disconnected controlled by Byte 1 bit[7:5]
2. Output enable control /OE is disable(/OE=High), pull down all channels
3. No normal operation voltage input (but standby voltage SVDD is still On), pull down all channels
