Table 83. FIFO_CTRL register description
FMODE [2:0] FIFO mode selection bits. Default value: 000
For further details refer to Table 84.
FTH [4:0] FIFO threshold level setting. Default value: 0 0000
Table 84. FIFO mode selection
FMODE2 FMODE1 FMODE0 Mode
0 0 0 Bypass mode. FIFO turned off
0 0 1 FIFO mode. Stops collecting data when FIFO is full.
0 1 0 Reserved
0 1 1 Continuous mode until trigger is deasserted, then FIFO
mode.
1 0 0 Bypass mode until trigger is deasserted, then Continuous
mode.
1 1 0 Continuous mode. If the FIFO is full, the new sample over-
writes the older sample.
