10.1. ATE Test Mode
The STAC9752A/9753A has two test modes. One is for ATE in-circuit test and the other is restricted
for IDT’s internal use. STAC9752A/9753A enters the ATE in-circuit test mode if SDATA_OUT is
sampled high at the trailing edge of RESET#. Once in the ATE test mode, the digital AC-Link outputs
(BIT_CLK and SDATA_IN) are driven to a high impedance state. This allows ATE in-circuit testing of
the AC'97 controller. Use of the ATE test mode is the recommended means of removing the CODEC
from the AC-Link when another CODEC is to be used as the primary. This case will never occur dur-
ing standard operating conditions. Once either of the two test modes have been entered, the
STAC9752A/9753A must be issued another RESET# with all AC-Link signals held low to return to
the normal operating mode.
ATE test mode allows for in-circuit testing to be completed at board level. For this to work, the out-
puts of the device must be driven to a high impedance state (Z). Internal pullups for digital I/O pins
must be disabled in this mode. This mode initiates on the rising edge of RESET# pin. Only a cold
reset will exit the ATE Test Mode.
Note: Pins 31, 33, and 34 are NO CONNECTS.
