Notes:

2.
All AC-Link signals are normally low through the trailing edge of RESET#. Bringing
SDATA_OUT high for the trailing edge of RESET# causes STAC9708/11’s AC-Link outputs to go
high impedance which is suitable for ATE in circuit testing.
Once either of the two test modes have been entered, the STAC9708/11 must be issued another
RESET# with all AC-Link signals low to return to the normal operating mode.
# denotes active low.
