7, 6 CODEC

TESTING

CONTROL

Codec Testing Controls. Set bits to 0 for normal operation. For details of testing

functions, see the MT8967 integrated PCM Filter/Codec data sheet.

3 SD3

(RD4)

2 SD2

(RD3)

When logic ‘0’, SD3 goes to the open state which deactivates the internal relay

driver 4, RD4 output goes to the open state.

When logic ‘0’ SD2 goes to AGND which deactivates the internal relay driver 3,

RD3 output goes to the open state.

1 SD1

(RD2)

0 SD0

(RD1)

A logic ‘0’, SD1 goes to AGND which deactivates the internal relay driver 2, RD2

output goes to the open state.

A logic ‘1’, SD1 goes to VDD which activates the internal relay driver 2, RD2 output

goes to RGND.

A logic ‘0’, SD0 goes to AGND which deactivates the internal relay driver 1, RD1

output goes to the open state.

A logic ‘1’, SD0 goes to VDD which activates the internal driver 1, RD1 output goes

to RGND.
