[7] 0 = No interrupt
1 = Internal buffer overflow
SPDIFIN internal buffer(s)
(SPDIFIN_DATA_BUF_x) overflows if HDMI fails
to transfer data from buffer(s) to memory on
time.
- This interrupt is asserted only if
SPDIFIN_OP_CTRL.op_ctrl is set to "011".
- If this interrupt is not handled, SPDIFIN
overwrites the next subframe data to internal
data buffer (SPDIFIN_DATA_BUF_x) and
continues data transfer via HDMI.
[6] Reserved
[5] Reserved
[4] 0 = No interrupt
1 = Detects stream data header (Pa~Pd)
- This interrupt is asserted if
SPDIFIN_OP_CTRL.op_ctrl is equal to 001b or
011b.
- Cases for interrupt
Case1: Initially after power_on
Case2: Next stream header at right time if
receiving stream data with
SPDIFIN_CONFIG.data_type set as 'stream
mode'
Case3: Initially detects stream header if
receiving stream data with
SPDIFIN_CONFIG.data_type is set as 'PCM
mode'
[3] 0 = No interrupt
1 = Does not detect stream data header for 4096
repetition time
- This interrupt will be asserted if
SPDIFIN_OP_CTRL.op_ctrl is equal to 001b or
011b.
- Cases for interrupt
Case1: Initially after power_on
Case2: SPDIFIN receives the stream but is
unable to find the next stream header for 4096
repetition time since previous stream header
Case3: Is unable to find stream header for 4096
repetition time since previous reset of repetition
time counter after previous interrupt of
'stream_header_not_detected_ir'.
