WSEQ_ENA
0
Write Sequencer Enable.
0 = Disabled
1 = Enabled
9
WSEQ_ABORT
0
Writing a 1 to this bit aborts the current sequence and
returns control of the device back to the serial control
interface.
8
WSEQ_START
0
Writing a 1 to this bit starts the write sequencer at the index
location selected by WSEQ_START_INDEX. The sequence
contin
ues until it reaches an “End of sequence” flag. At the
end of the sequence, this bit will be reset by the Write
Sequencer.

WSEQ_START_
INDEX [6:0]
000_0000
Sequence Start Index. This field determines the memory
location of the first command in the selected sequence.
There are 127 Write Sequencer RAM addresses:
00h = WSEQ_ADDR0 (R12288)
01h = WSEQ_ADDR1 (R12292)
02h = WSEQ_ADDR2 (R12296)

Note: it is not possible to write to control registers via the
control interface while the Sequencer is Busy.

WSEQ_CURRE
NT_INDEX [6:0]
000_0000
Sequence Current Index. This indicates the memory
location of the most recently accessed command in the
write sequencer memory.
Coding is the same as WSEQ_START_INDEX.
