WSEQ_DATA[

7:0]

0000_0000 Data to be written in this sequence step. When the 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.

Sequencer 3

WSEQ_ABOR

Writing a 1 to this bit aborts the current sequence and

returns control of the device back to the serial control

interface.

WSEQ_START

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.
