D[1:0]
FIFO trigger level (sweep sequence length). Don’t care in one shot mode.
00: Full (INT generated after FIFO Level 7 filled)
01: 3/4 (INT generated after FIFO Level 5 filled)
10: 1/2 (INT generated after FIFO Level 3 filled)
11: 1/4 (INT generated after FIFO Level 1 filled)
sampling period
The sampling period follows the command period. The selected signal is sampled during this time. The device
has three different sampling modes: normal short mode, normal long mode, and extended mode.
Normal Short Sampling Mode: Sampling time is controlled by the SCLK and lasts 12 SCLK periods. At the
end of sampling, the converter automatically starts the conversion period. After the configuration, the normal
sampling starts automatically after the falling edge of fourth SCLK that follows the falling edge of CS if CS
triggers the operation, or follows the rising edge of FS if FS initiates the operation, except the FIFO READ and
WRITE CFR commands.
