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.

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.
