SPDIFIN_IRQ_STATUS Bit Description Reset Value
Case2 = Next stream header at right time if stream data
received with SPDIFIN_CONFIG.data_type set as
‘stream mode’.
Case3 = Initially detected stream header if stream data
received with SPDIFIN_CONFIG.data_type set as ‘PCM
mode’.

0 = No interrupt
1 = Stream data header not detected for 4096 repetition
time
Writing ‘0’ has no effect. Writing ‘1’ clears the interrupt
request.
- This interrupt assertes if
SPDIFIN_OP_CTRL.op_ctrl=001b or 011b.
- Cases for interrupt
Case1 = Initially after power_on
Case2 = SPDIFIN was receiving stream but could not
find next stream header for 4096 repetition time since
previous stream header
Case3 = Cannot find stream header for 4096 repetition
time since previous reset of repetition time counter after
previous interrupt of ‘stream_header_not_detected_ir’.
0
wrong_preamble_ir 2
0 = No interrupt
1 = Detects Preamble but there is a problem with
detected time
Writing ‘0’ has no effect. Writing ‘1’ clears the interrupt
request.
- This interrupt assertes if
SPDIFIN_OP_CTRL.op_ctrl=001b or 011b.
- Meaningless until ch_status_recovered_ir is asserted
initially after SPDIFIN_OP_CTRL. op_ctrl=01b
- Cases for interrupt
Case1 = Deetcts preamble in the middle of a subframe
audio sample word time
Case2 = Next preamble was not detected at exact time
after a subframe duration
Case3 = It was time for preamble B(or M or W) to be
detected but other preamble was detected at that time
0
ch_status_recovered_ir 1
0 = No interrupt
1 = Recovered channel status
Writing ‘0’ has no effect. Writing ‘1’ clears the interrupt
request.
Detectes preamble of 2 consecutive B-preamble thus
recovered 192-bit wide channel status.
- Only supports consumer mode, therefore just 36-bits
are reconstructed. If you want to see the channel status
bits through SPDIFIN_CH_STATUS_x, better read two
