tion of the control and status fields of the AO unit. To en-
sure compatibility with future devices, any undefined or
reserved MMIO bits should be ignored when read, and
written as zeroes
The AO unit is reset by a PNX1300 hardware reset, or by
writing 0x80000000 to the AO_CTL register. The AO unit
is not affected by DSPCPU reset initiated through the
BIU_CTL register. Either reset method sets all MMIO
fields as indicated in the tables.
The timestamp counter is reset by TRI_RESET# or by
DSPCPU reset initiated through BIU_CTL. It is not affect-
ed by AO_CTL reset. This ensures that the timestamp

After an AO reset, 5 AO_SCK clock cycles are required
to stabilize the internal circuitry before enabling Audio
Out. This can be accomplished by programming the
AO_FREQ and AO_SERIAL registers to start AO_SCK
generation then waiting for the appropriate 5 AO_SCK
cycle interval.
Programing of the AO_SERIAL MMIO register needs to
follow the following sequence order:
• set AO_FREQ to ensure that a valid clock is gener-
• MMIO(AO_CTL)

system)
