Notes:

1. All AC-link signals are normally low through the trailing edge of RESET#.

Bringing

SDATA_OUT high for the trailing edge of RESET# causes STAC9704/7’s AC-link outputs to go

high impedance which is suitable for ATE in circuit testing.

2. Once either of the two test modes have been entered, the STAC9704/7 must be issued another

RESET# with all AC-link signals low to return to the normal operating mode.

# denotes active low.
