NEW_AUDIO_INFO_ST, IO, Address 0x7A[1] (Read Only)
Latched status for the new audio InfoFrame interrupt. Once set, this bit will remain high until the interrupt is cleared via
NEW_AUDIO_INFO_CLR. This bit is only valid if enabled via the corresponding INT1 or INT2 interrupt mask bit.
Function
NEW_AUDIO_INFO_ST
0 (default)
1
NEW_AVI_INFO_ST, IO, Address 0x7A[0] (Read Only)
HDMI Edg INT Status 2 register consists of fields: FIFO_NEAR_OVFL_ST, FIFO_UNDERFLO_ST, FIFO_OVERFLO_ST,
CTS_PASS_THRSH_ST, CHANGE_N_ST, PACKET_ERROR_ST, AUDIO_PCKT_ERR_ST, and NEW_GAMUT_MDATA_ST.
FIFO_NEAR_OVFL_ST, IO, Address 0x7F[7] (Read Only)
Latched status for the audio FIFO near overflow interrupt. Once set, this bit will remain high until the interrupt is cleared via
FIFO_OVFL_CLR. This bit is only valid if enabled via the corresponding INT1 or INT2 interrupt mask bit.
Function
FIFO_NEAR_OVFL_ST
0 (default)
1
FIFO_UNDERFLO_ST, IO, Address 0x7F[6] (Read Only)
Latched status for the sudio FIFO underflow interrupt. Once set, this bit will remain high until the interrupt is cleared via
FIFO_UNDERFLO_CLR. This bit is only valid if enabled via the corresponding INT1 or INT2 interrupt mask bit.
Function
FIFO_UNDERFLO_ST
0 (default)
1
FIFO_OVERFLO_ST, IO, Address 0x7F[5] (Read Only)
Latched status for the audio FIFO overflow interrupt. Once set, this bit will remain high until the interrupt is cleared via
FIFO_OVERFLO_CLR. This bit is only valid if enabled via the corresponding INT1 or INT2 interrupt mask bit.
Function
FIFO_OVERFLO_ST
0 (default)
1
CTS_PASS_THRSH_ST, IO, Address 0x7F[4] (Read Only)
Latched status for the ACR CTS value exceed threshold interrupt. Once set, this bit will remain high until the interrupt is cleared via
CTS_PASS_THRSH_CLR. This bit is only valid if enabled via the corresponding INT1 or INT2 interrupt mask bit.
Function
CTS_PASS_THRSH_ST
0 (default)
1
CHANGE_N_ST, IO, Address 0x7F[3] (Read Only)
Latched status for the ACR N value changed interrupt. Once set, this bit will remain high until the interrupt is cleared via
CHANGE_N_CLR. This bit is only valid if enabled via the corresponding INT1 or INT2 interrupt mask bit.
Function
CHANGE_N_ST
0 (default)
1
