Description
Encodes function of fgpi_start / fgpi_rec_start pin
Record Mode (fgpi_rec_start):
Message Mode (fgpi_start):
1 = Write Timestamp before record/message data. Timestamp is a
4-byte time-of-arrival for fgpi_rec_start / fgpi_start event. If this bit
and bit-0 below (VAR_LENGTH) are both set the Timestamp is
written before the length.
Note: The length of the Timestamp (4 bytes) IS NOT included in the
record/message size in FGPI_SIZE register but IS included in the
stride (FGPI_STRIDE register).
1 = The length of each record/message (in samples) is written
before record/message data. Var_length is a 4-byte count. If this bit
and bit-1 above (TSTAMP_SELECT) are both set the Timestamp is
written before the length.
Note: The length of var_length (4 bytes) IS NOT included in the
record/message size in FGPI_SIZE register but IS included in the
stride (FGPI_STRIDE register).
32-bit word aligned address pointing to Buffer 1 base.
To ensure software backward compatibility unused or reserved bits
must be written as zeros and ignored upon read.
32-bit word aligned address pointing to Buffer 2 base.
To ensure software backward compatibility unused or reserved bits
must be written as zeros and ignored upon read.
00 = Start record on rising edge on fgpi_rec_start
01 = Start record on falling edge on fgpi_rec_start
10 = No record sync. Switch to next record if current buffer is full.
Start first record immediately after enable.
11 = same as 10 above
00 = Start message on rising edge of fgpi_start
01 = Start message on falling edge of fgpi_start
10 = same as 00 above.
11 = same as 01 above.
