3.9.15.17 One-shot Sequencer Parameter Restrictions
When using the One-shot Sequencer, 0xA must be set in the corresponding START_INTERVALn (n is the
sequencer number) fields of the START_INTERVAL3_0, START_INTERVAL7_4, and
START_INTERVAL9_8 registers within the SCU_REG.
When this setting has been made, the OLDEST_TIMESTAMP cannot be used because its value cannot be
correctly calculated by the sequencer using the same Write FIFO number as the ADC.
(refer to Section 3.9.15.9)
With the One-shot Sequencer, captured data cannot be passed through the MATH_PROC.
3.9.15.18 FIFO Points of Attention
3.9.15.18.1 FIFO Initialization
Initialization of the Write FIFO and Read FIFO have the following restrictions in terms of their order.

Make sure to perform reset (*_R*_*_CTRL1.FIFO_RESET) of the readout side FIFO after initializing the
writing side FIFO.
Before performing reset of the readout side, the initial setting of the Write FIFO must be completed because the
hardware uses the reset of the readout side FIFO as the trigger to copy the pointer of the writing side FIFO to the
readout side. Initialization of the writing side FIFO means the below sequences.
Table SCU (Sensor Control Unit)-728 Write FIFO Initialization (excluding virtual partition)
Order Initialization Process
1 Partition start address selection
2 Partition size selection
3 Selection of number of bytes per sample
4 Selection of operation mode during FIFO full
5 FIFO writing side reset
Make the Read FIFO initial settings in the following order.
Order Initialization Process
1 Watermark setting
2 Writing side FIFO reset
