Setup to trailing edge of RESET# (also applies to SYNC)
Rising edge of RESET# to Hi-Z delay
End of Slot 2 to BIT_CLK, SDATA_IN low

Note: 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 the STAC9766/9767 AC-Link outputs to
go high-impedance, which is suitable for ATE in-circuit testing.
Note: 2) Once the test mode has been entered, the STAC9766/9767 must be issued another
RESET# with all AC-Link signals low to return to the normal operating mode.
Note: 3) # denotes active low.
