8.3.4
AC-link low power mode
The AC-link signals can be placed in a low power mode. When the UCB1400’s PR4
bit is set to ‘1’ in the Power-down status and control register (0x26), both BIT_CLK
and SDATA_IN will be brought to, and held at, a logic LOW voltage level.
BIT_CLK and SDATA_IN are transitioned low immediately following the decode of the
write to Register 0x26 with PR4. When the AC ’97 Controller driver is at the point
where it is ready to program the AC-link into its low power mode, slots (1 and 2)
are
assumed to be
the only valid stream in the audio output frame.
The AC ’97 Controller should also drive SYNC and SDATA_OUT LOW after
programming UCB1400 AC ’97 to this low power, halted mode. The AC ’97 Controller
is required to drive and keep SYNC and SDATA_OUT LOW in this low power, halted
mode.
Once the UCB1400 has been instructed to halt BIT_CLK, a special ‘wake-up’ protocol
must be used to bring the AC-link to the active mode since normal audio output and
input frames cannot be communicated in the absence of BIT_CLK.
