0 = HPD_SINK
1 = I²C Register Setting from B0b[0:3]
0
Under I2C register control mode,
HPD[A:C] can be individually control by
B0b[0:2] for HPD output.
0 = Open Drain
0
1 = Output Buffer
I. Byte0 b[4] = 1
When B0b[3] = 0 (open drain mode)
B0b[2]=0, set HPD [C] to Low
0
B0b[2]=1, set HPD [C] to High by
external pull high resistor
When B0b[3] = 1 (output buffer mode)
B0b[2]=0, set HPD [C] to High
B0b[2]=1, set HPD [C] to Low
I. Byte0 b[4] = 1
When B0b[3] = 0 (open drain mode)
B0b[1]=0, set HPD [B] to Low
0
B0b[1]=1, set HPD [B] to High by exter-
nal pull high resistor
When B0b[3] = 1 (output buffer mode)
B0b[1]=0, set HPD [B] to High
B0b[1]=1, set HPD [B] to Low
I. Byte0 b[4] = 1
When B0b[3] = 0 (open drain mode)
B0b[0]=0, set HPD [A] to Low
0
B0b[0]=1, set HPD [A] to High by exter-
nal pull high resistor
When B0b[3] = 1 (output buffer mode)
B0b[0]=0, set HPD [A] to High
B0b[0]=1, set HPD [A] to Low
