POWER-DOWN FRAME
Before enabling wake-up via IRQOUT or GIEN bit, the UCB1400 must be enabled for
interrupt by setting the appropriate bits in the Positive INT Enable register (0x5E) and
Negative INT Enable register (0x60). The INT Clear/Status register (0x62) should
then be cleared of any previous interrupts before going to low-power mode.
AC ’97 Component Specification defines two test modes. One is for ATE in-circuit
test, and the other if for vendor-specific tests. The UCB1400 enters the ATE in-circuit
test mode if SDATA_OUT is sampled HIGH at the trailing edge of RESET. The
UCB1400 enters the vendor-specific test mode when coming out of reset if SYNC is
HIGH. These cases will never occur during standard operating conditions.
Regardless of the test mode, the AC ’97 Controller must issue a cold reset to resume
normal operation of the UCB1400.
When the UCB1400 is placed in the ATE test mode, its digital AC-link outputs (i.e.,
BIT_CLK and SDATA_IN) shall be driven to a high impedance state. This allows ATE
in-circuit testing of the AC ’97 Controller.
When the UCB1400 is placed in the vendor-specific test mode, the Test Control
register (Index 0x6E) determines the kind of tests to be performed.
