DESCRIPTION
8 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.
7
WSEQ_START
0
Writing a 1 to this bit starts the write sequencer at the index
location selected by WSEQ_START_INDEX. 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.
6:0 WSEQ_START_ 000_0000 Sequence Start Index. This field determines the memory
INDEX [6:0]
location of the first command in the selected sequence.
There are 127 Write Sequencer RAM addresses:
00h = WSEQ_ADDR0 (R4096)
01h = WSEQ_ADDR1 (R4100)
02h = WSEQ_ADDR2 (R4104)
….
7Fh = WSEQ_ADDR127 (R4604)

DESCRIPTION
9:3 WSEQ_CURRE 000_0000 Sequence Current Index. This indicates the memory
NT_INDEX [6:0]
location of the most recently accessed command in the
write sequencer memory.
Coding is the same as WSEQ_START_INDEX.
0
WSEQ_BUSY
0
Sequencer Busy flag (Read Only).
0 = Sequencer idle
1 = Sequencer busy
Note: it is not possible to write to non-PLL control registers
via the control interface while the Sequencer is Busy.
