Section 25 Audio Codec Interface (HAC)
Section 25 Audio Codec Interface (HAC)
The HAC, the audio codec digital controller interface, supports bidirectional data transfer
compliant with Audio Codec 97 (AC'97) Version 2.1. The HAC provides serial transmission to
/reception from the AC97 codec. Each channel of the HAC can be connected to a single audio
codec device.
The HAC carries out data extraction from/insertion into audio frames. For data slots within both
receive and transmit frames, the PIO transfer by the CPU or the DMA transfer by the DMAC can
be used.
25.1
Features
The HAC has the following features:
• Digital interface to a single AC'97 version 2.1 Audio Codec
• PIO transfer of status slots 1 and 2 in Rx frames
• PIO transfer of command slots 1 and 2 in Tx frames
• PIO transfer of data slots 3 and 4 in Rx frames
• PIO transfer of data slots 3 and 4 in Tx frames
• Selectable 16-bit or 20-bit DMA transfer of data slots 3 and 4 in Rx frames
• Selectable 16-bit or 20-bit DMA transfer of data slots 3 and 4 in Tx frames
• Accommodates various sampling rates by qualifying slot data with tag bits and monitoring the
Tx frame request bits of Rx frames
• Generates data ready, data request, overrun and underrun interrupts
• Supports cold reset, warm reset, and power-down mode
