End of Sequence flag. This bit indicates whether
the Control Write Sequencer should stop after
executing this step.
0 = Not end of sequence
1 = End of sequence (Stop the sequencer after this
step).
Time delay after executing this step.
Total delay time per step (including execution)=
62.5μs × (2^WSEQ_DELAY + 8)
data width is less than 8 bits, then one or more of
the MSBs of WSEQ_DATA are ignored. It is
recommended that unused bits be set to 0.
Writing a 1 to this bit aborts the current
sequence and returns control of the device
back to the serial control interface.
Writing a 1 to this bit starts the write
sequencer at the memory location indicated
by the WSEQ_START_INDEX field. The
sequence continues until it reaches an “End
of sequence” flag. At the end of the
sequence, this bit will be reset by the Write
Sequencer.
Sequence Start Index. This is the memory
location of the first command in the selected
sequence.
