Description
0 = The REC_SYNC and BUF_SYNC fields control record/message
sync and buffer sync events.
1 = Overrides BUF_SYNC to “No Sync mode: 000”, REC_SYNC
field is ignored. Causes the FGPO to read an 8-byte record/
message header where the first 4-bytes contains the 32-bit
timestamp word. Record/message will start when the internal
timestamp matches the timestamp in the header.
Note: The length of the header (8 bytes) IS NOT included in the
record/message size in FGPO_SIZE register but IS included in the
stride (FGPO_STRIDE register).
0 = The length of each record/message is contained in the
FGPO_REC_SIZE register.
1 =Causes the FGPO to read an 8-byte record/message header
where the second 4-bytes contains the 32-bit record/message
length word.
Note: The length of the header (8 bytes) IS NOT included in the
record/message size in FGPO_SIZE register but IS included in the
stride (FGPO_STRIDE register).
32-bit word aligned address pointing to Buffer 1 base.
Always 0.
32-bit word aligned address pointing to Buffer 2 base.
Always 0.
To ensure software backward compatibility unused or reserved bits
must be written as zeros and ignored upon read.
Number of records/messages per buffer. Range: 1 to 2
To ensure software backward compatibility unused or reserved bits
must be written as zeros and ignored upon read.
Number of samples per record/message. Range: 2 to 2
Address stride between records/messages
Record mode:
The value read from the header overrides the contents of the
FGPO_REC_SIZE register.
Message mode:
If the message length read from the header is greater than the
value in the FGPO_REC_SIZE register then the message is
truncated to FGPO_REC_SIZE samples.
