Bit
Description
D5 and D4 channel 1 DC load or AC load detection
if bit IB1[D2] = 1, AC load detection is enabled, bit D5 is don’t care, bit D4 has the
following meaning
0 = no AC load
1 = AC load detected
if bit IB1[D2] = 0, AC load detection is disabled, bits D5 and D4 are available for
DC load detection
00 = normal load
01 = not valid
10 = line driver load
11 = open load
D3
channel 1 shorted load
0 = not shorted load
1 = shorted load
D2
channel 1 output offset
0 = no output offset
1 = output offset
D1
channel 1 short to V_P
0 = no short to V_P
1 = short to V_P
D0
channel 1 short to ground
0 = no short to ground
1 = short to ground
