Page 0/Register 38: High-Power Output Driver Control Register
BIT READ/ RESET DESCRIPTION
WRITE VALUE
D7 – D6 R 00 Reserved. Write only zeros to these bits.
D5 – D3 R/W 000 HPRCOM Output Driver Configuration Control
000: HPRCOM is configured as differential of HPROUT.
001: HPRCOM is configured as constant VCM output.
010: HPRCOM is configured as independent single-ended output.
011: HPRCOM is configured as differential of HPLCOM.
100: HPRCOM is configured as external feedback with HPLCOM as constant VCM output.
101 – 111: Reserved. Do not write these sequences.
D2 R/W 0 Short-Circuit Protection Control
0: Short-circuit protection on all high-power output drivers is disabled.
1: Short-circuit protection on all high-power output drivers is enabled.
D1 R/W 0 Short-Circuit Protection Mode Control
0: If short-circuit protection is enabled, it limits the maximum current to the load.
1: If short-circuit protection is enabled, it powers down the output driver automatically when a short is
detected.
D0 R 0 Reserved. Write only zero to this bit.
Page 0/Register 39: Reserved Register
BIT READ/ RESET DESCRIPTION
WRITE VALUE
D7 – D0 R 0000 0000 Reserved. Do not write to this register.

00: Output common-mode voltage = 1.35 V
01: Output common-mode voltage = 1.5 V
10: Output common-mode voltage = 1.65 V
11: Output common-mode voltage = 1.8 V
D5 – D2 R/W 0000 Reserved. Write only zeros to these bits.
D1 – D0 R/W 00 Output Volume Control Soft-Stepping
00: Output soft-stepping = one step per f
S
01: Output soft-stepping = one step per 2 f
S
10: Output soft-stepping is disabled.

Page 0/Register 41: DAC Output Switching Control Register
BIT READ/ RESET DESCRIPTION
WRITE VALUE
D7 – D6 R/W 00 Left-DAC Output Switching Control
00: Left-DAC output selects DAC_L1 path.
01: Left-DAC output selects DAC_L3 path to left line output driver.
10: Left-DAC output selects DAC_L2 path to left high-power output drivers.
11: Reserved. Do not write this sequence.
D5 – D4 R/W 00 Right-DAC Output Switching Control
00: Right-DAC output selects DAC_R1 path.
01: Right-DAC output selects DAC_R3 path to right line output driver.
10: Right-DAC output selects DAC_R2 path to right high-power output drivers.
11: Reserved. Do not write this sequence.
D3 – D2 R/W 00 Reserved. Write only zeros to these bits.
D1 – D0 R/W 00 DAC Digital Volume Control Functionality
00: Left- and right-DAC channels have independent volume controls.
01: Left-DAC volume follows the right-DAC digital volume control register.
10: Right-DAC volume follows the left-DAC digital volume control register.
11: Left- and right-DAC channels have independent volume controls (same as 00).
