Description
temperature pre-warning
speaker fault channel 2 (missing current)
channel 2 DC load or AC load detection
channel 2 shorted load
channel 2 output offset
channel 2 short to V
channel 2 short to ground
Description
power-on reset and amplifier status
speaker fault channel 4 (missing current)
0 = no warning
1 = junction temperature too high
0 = no missing current
1 = missing current
if bit IB1[D2] = 1, AC load detection is enabled, bit D5 is don’t care, bit D4 has the
following meaning
if bit IB1[D2] = 0, AC load detection is disabled, bits D5 and D4 are available for
DC load detection
0 = not shorted load
1 = shorted load
0 = no output offset
1 = output offset
0 = no short to V
1 = short to V
0 = no short to ground
1 = short to ground
0 = amplifier on
1 = power-on reset has occurred; amplifier off
0 = no missing current
1 = missing current
0 = no AC load
1 = AC load detected
00 = normal load
01 = not valid
10 = line driver load
11 = open load
