Connecting the MIC1LP/LINE1LP input signal to the LEFT_LOP pin is done by closing SW-L1 and opening SW-
L0; this action is done by writing a 1 to page 0, register 108, bit D0. Connecting the MIC2L/LINE2L input signal to
the LEFT_LOP pin is done by closing SW-L2 and opening SW-L0; this action is done by writing a 1 to page 0,
register 108, bit D2. Connecting the MIC1LM/LINE1LM input signal to the LEFT_LOM pin is done by closing SW-
L4 and opening SW-L3; this action is done by writing a 1 to page 0, register 108, bit D1.
Connecting the MIC1RP/LINE1RP input signal to the RIGHT_LOP pin is done by closing SW-R1 and opening
SW-R0; this action is done by writing a 1 to page 0, register 108, bit D4. Connecting the MIC2R/LINE2R input
signal to the RIGHT_LOP pin is done by closing SW-R2 and opening SW-R0; this action is done by writing a 1 to
page 0, register 108, bit D6. Connecting MIC1RM/LINE1RM input signal to the RIGHT_LOM pin is done by
closing SW-R4 and opening SW-R3; this action is done by writing a 1 to page 0, register 108, bit D5. A diagram
of the passive analog bypass mode configuration is shown in Figure 29.
In general, connecting two switches to the same output pin should be avoided, as this error shorts two input
signals together, and would likely cause distortion of the signal as the two signals are in contention. Poor
frequency response would also likely occur.
