InfoFrame Collection Mode
The
ADV7610
has two modes for storing the InfoFrame packet sent from the source into the internal memory. By default, the
only stores the InfoFrame packets received if the checksum is correct for each InfoFrame.
The
ADV7610
also provides a mode to store every InfoFrame sent from the source, regardless of a InfoFrame packet checksum error.
ALWAYS_STORE_INF, Addr 68 (HDMI), Address 0x47[0]
A control to force InfoFrames with checksum errors to be stored.
Function
ALWAYS_STORE_INF
0 (default)

InfoFrame Checksum Error Flags
The following checksum error status registers flag when the last InfoFrame received has a checksum error. Once set, these bits remain
high until the interrupt is cleared via their corresponding clear bits.
AVI_INF_CKS_ERR_RAW, IO, Address 0x88[4] (Read Only)
Status of AVI InfoFrame checksum error interrupt signal. When set to 1, it indicates that a checksum error has been detected for an AVI
InfoFrame. Once set, this bit remains high until it is cleared via AVI_INF_CKS_ERR_CLR.
Function
AVI_INF_CKS_ERR_RAW
0 (default)
1
AUD_INF_CKS_ERR_RAW, IO, Address 0x88[5] (Read Only)
Status of audio InfoFrame checksum error interrupt signal. When set to 1, it indicates that a checksum error has been detected for an
audio InfoFrame. Once set, this bit remains high until it is cleared via AUDIO_INF_CKS_ERR_CLR.
Function
AUD_INF_CKS_ERR_RAW
0 (default)
1
SPD_INF_CKS_ERR_RAW, IO, Address 0x88[6] (Read Only)
Status of SPD InfoFrame checksum error interrupt signal. When set to 1, it indicates that a checksum error has been detected for an SPD
InfoFrame. Once set, this bit remains high until it is cleared via ASPD_INF_CKS_ERR_CLR.
Function
SPD_INF_CKS_ERR_RAW
0 (default)
1
MS_INF_CKS_ERR_RAW, IO, Address 0x88[7] (Read Only)
Status of MPEG source InfoFrame checksum error interrupt signal. When set to 1. it indicates that a checksum error has been detected for
an MPEG source InfoFrame. Once set, this bit remains high until it is cleared via MS_INF_CKS_ERR_CLR.
Function
MS_INF_CKS_ERR_RAW
0 (default)
1
