STA310
This register is used to set the value of the status bit in the IEC958 data stream.
SPDIF_REP_TIME
SPDIF repetition time of a pause frame
Address: 0x75
Type: R/W
Software Reset: NC
Hardware: Reset: UND
Description:
In compressed mode, a burst of pause frames is sent when there are no more data to transmit (due to an error
or a gap in the incoming bitstream, for example).
This register sets the size of a pause frame in IEC frames: Dolby Digital =4, MPEG=32 and DTS=3.
SPDIF_LATENCY
Latency value
Address: 0x7E
Type: R/W
Software Reset: NC
Hardware: Reset: UND
Description:
If bit LAT of register SPDIF_CONF is set, a delay can be configured between the output of IEC61937 in com-
pressed mode and the output of the audio decoder. To configure a latency (in unit of seconds) this register has
to be set according the following formula:
Value = L x FS/8 where, L=Latency in s and FS=Sampling frequency in Hz
