TEST REGISTER CR5 DESCRIPTION
Note: Test register is intended only for internal testing of the device and not supposed to be used in
normal operation. It is strongly recommended not to change initial test register value (00hex).
XMUTE pin is output pin when bit 1 is set in register CR5. Bits 2, 3 and 4 select different internal signals. In test
phase those signals can be seen via XMUTE pin.

Normal operation
Force latch, note 1
left delay generator
left peak detector
left zero crossing
left enable for zero crossing
and delay generator
right delay generator
right peak detector
right zero crossing
right enable for zero crossing
and delay generator
Note 1.
Forces the new gain value to be latched to resistor network without waiting for zero crossing or delay generator. LSB bit has to be
returned to 0 before next gain value can be latched. When force latch is used, both channels are latched with the same value.
ABSOLUTE MAXIMUM RATINGS
