NEW_SAMP_RT_ST , IO, Address 0x84[3] (Read Only)
Latched status of new sampling rate interrupt. Once set, this bit will remain high until the interrupt is cleared via NEW_SAMP_RT_CLR.
This bit is only valid if enabled via the corresponding INT1 or INT2 interrupt mask bit.
Function
NEW_SAMP_RT_ST
0 (default)
1
AUDIO_FLT_LINE_ST , IO, Address 0x84[2] (Read Only)
Latched status of new TMDS frequency interrupt. Once set, this bit will remain high until the interrupt is cleared via
NEW_TMDS_FREQ_CLR. This bit is only valid if enabled via the corresponding INT1 or INT2 interrupt mask bit.
Function
AUDIO_FLT_LINE_ST
0 (default)
1
NEW_TMDS_FRQ_ST , IO, Address 0x84[1] (Read Only)
Latched status of new TMDS frequency interrupt. Once set, this bit will remain high until the interrupt is cleared via
NEW_TMDS_FREQ_CLR. This bit is only valid if enabled via the corresponding INT1 or INT2 interrupt mask bit.
Function
NEW_TMDS_FRQ_ST
0 (default)
1
FIFO_NEAR_UFLO_ST , IO, Address 0x84[0] (Read Only)
Latched status for the audio FIFO near underflow interrupt. Once set, this bit will remain high until the interrupt is cleared via
FIFO_UFLO_CLR. This bit is only valid if enabled via the corresponding INT1 or INT2 interrupt mask bit.
Function
FIFO_NEAR_UFLO_ST
0 (default)
1
HDMI Edg Status 4 register consists of fields: MS_INF_CKS_ERR_ST, SPD_INF_CKS_ERR_ST, AUD_INF_CKS_ERR_ST,
AVI_INF_CKS_ERR_ST, RI_EXPIRED_A_ST, and AKSV_UPDATE_A_ST.
MS_INF_CKS_ERR_ST , IO, Address 0x89[7] (Read Only)
Latched status of MPEG source InfoFrame checksum error interrupt. Once set, this bit will remain high until the interrupt is cleared via
MS_INF_CKS_ERR_CLR. This bit is only valid if enabled via the corresponding INT1 or INT2 interrupt mask bit.
Function
MS_INF_CKS_ERR_ST
0 (default)
1
SPD_INF_CKS_ERR_ST , IO, Address 0x89[6] (Read Only)
Latched status of SPD InfoFrame checksum error interrupt. Once set, this bit will remain high until the interrupt is cleared via
SPD_INF_CKS_ERR_CLR. This bit is only valid if enabled via the corresponding INT1 or INT2 interrupt mask bit.
Function
SPD_INF_CKS_ERR_ST
0 (default)
1
AUD_INF_CKS_ERR_ST , IO, Address 0x89[5] (Read Only)
Latched status of audio InfoFrame checksum error interrupt. Once set, this bit will remain high until the interrupt is cleared via
AUDIO_INF_CKS_ERR_CLR. This bit is only valid if enabled via the corresponding INT1 or INT2 interrupt mask bit.
