33.5 Operation
33.5.1 Receiver
The HAC receiver receives serial audio data input on the HAC_SD_IN pin, synchronous to
HAC_BITCLK. From slot 0, the receiver extracts tag bits that indicate which other slots contain
valid data. It will update the receive data only when receiving valid slot data indicated by the tag
bits.
Supporting data only in slots 1 to 4, the receiver ignores tag bits and data related to slots 5 to 12. It
loads valid slot data to the corresponding shift register to hold the data for PIO or DMA transfer,
and sets the corresponding status bits. It is possible to read 20-bit data within a 32-bit register
using PIO.
In the case of RX overrun, the new data will overwrite the current data in the RX buffer of the
HAC.
