Description
• Isochronous low latency bus master memory interface
• Scatter/gather support for word-aligned buffers in memory
(all mono or stereo 20-bit and 16-bit data types are supported, no 8-bit
data types are supported)
• Data buffer size in system memory from 3 to 65535 samples per input
• Data buffer size in system memory from 0 to 65535 samples per output
• Independent PCI audio and modem functions with configuration and IO
spaces
• AC’97 codec registers are shadowed in system memory through driver.
• AC’97 codec register accesses are serialized through semaphore bit in PCI
IO space (new accesses are not allowed while a prior access is still in
progress).
• Power management through PCI Power Management
• Read/write access to audio codec registers 00h-3Ah and vendor registers
5Ah-7Eh
• 20-bit stereo PCM output, up to 48 KHz (L,R, Center, Sub-woofer, L-rear
and R-rear channels on slots 3,4,6,7,8,9,10,11)
• 16-bit stereo PCM input, up to 48 KHz (L,R channels on slots 3,4)
• 16-bit mono mic in w/ or w/o mono mix, up to 48 KHz (L,R channel, slots
3,4) (mono mix supports mono hardware AEC reference for speakerphone)
• 16-bit mono PCM input, up to 48 KHz from dedicated mic ADC (slot 6)
(supports speech recognition or stereo hardware AEC ref for
speakerphone)
• During cold reset AC_RST# is held low until after POST and software
deassertion of AC_RST# (supports passive PC_BEEP to speaker connection
during POST).
