1
Vendor specific D5 power state, only entered once the part is already in D3cold
(this bit must be set before the command to enter D3cold). If set, this bit over-
rides the D4 bit (bit 0). Includes the power savings of D4, but additionally pow-
ers down GPIO pins, the VAG amp, and the HP amps. Exits this power state
via POR or rising edge of Link Reset.
0
Vendor specific D4 power state, only entered once the part is already in D3cold
(this bit must be set before the command to enter D3cold). If the D5 bit (bit 1)
is set, this bit is overridden. Includes the power savings of D3cold, but addi-
tionally powers down the HDA interface (no responses). Exit this power state
via POR or rising edge of Link Reset.
