BIT READ/ RESET DESCRIPTION
WRITE VALUE
D7 R/W 0 Reserved. Write only zero to this register bit.
D6 R/W 0 LINE2RP Path Selection
0: Normal Signal Path
1: Signal is routed by a switch to RIGHT_LOP
D5 R/W 0 Reserved. Write only zero to this register bit.
D4 R/W 0 LINE1RP Path Selection
0: Normal Signal Path
1: Signal is routed by a switch to RIGHT_LOP
D3 R/W 0 LINE2LM Path Selection
0: Normal Signal Path
1: Signal is routed by a switch to LEFT_LOM (Internal Signal)
D2 R/W 0 LINE2LP Path Selection
0: Normal Signal Path
1: Signal is routed by a switch to LEFT_LOP
D1 R/W 0 LINE1LM Path Selection
0: Normal Signal Path
1: Signal is routed by a switch to LEFT_LOM (Internal Signal)
D0 R/W 0 LINE1LP Path Selection
0: Normal Signal Path
1: Signal is routed by a switch to LEFT_LOP
(1) Based on the setting above, if BOTH LINE1 and LINE2 inputs are routed to the output at the same time, then the two switches used for
the connection short the two input signals together on the output pins. The shorting resistance between the two input pins is two times
the bypass switch resistance (R
DS(on)
). In general this condition of shorting should be avoided, as higher drive currents are likely to
occur on the circuitry that feeds these two input pins of this device.

BIT READ/ RESET DESCRIPTION
WRITE VALUE
D7-D6 R/W 00 DAC Current Adjustment
00: Default
01: 50% increase in DAC reference current
10: Reserved
11: 100% increase in DAC reference current
D5-D0 R/W 000000 Reserved. Write only zero to these register bits.

BIT READ/ RESET DESCRIPTION
WRITE VALUE
D7-D1 X 0000000 Reserved, write only zeros to these register bits
D0 R/W 0 Page Select Bit
Writing zero to this bit sets Page-0 as the active page for following register accesses. Writing a one to
this bit sets Page-1 as the active page for following register accesses. It is recommended that the user
read this register bit back after each write, to ensure that the proper page is being accessed for future
register read/writes. This register has the same functionality on page-0 and page-1.
