on page 64 for information about using custom test

bit stream data sets.

Sample Command:

Write test bit stream data 0x000000, 0x0007DA,

0x000FB5, 0x00178F.

02 03 00 00 06 00 00 04

Delay 1 ms, monitor SINT, or poll E2DREQ

02 06 00 00 00 00 07 DA

Delay 1 ms, monitor SINT, or poll E2DREQ

02 06 00 0F B5 00 17 8F

Delay 1 ms, monitor SINT, or poll E2DREQ

Write TBS ROM Data - 0x07

This command selects the on-chip test bit stream

(TBS) data for use by the TBS generator. No data

words are required for this configuration com-

mand. See “Test Bit Stream Generator” on page 64

for information about the on-chip test bit stream

data set.

Sample Command:

02 03 00 00 07

Delay 1 ms, monitor SINT, or poll E2DREQ

Filter Start - 0x08

This command initializes and starts the digital fil-

ter. Measurement data becomes available one full

sample period after this command is issued. No

data words are required for this configuration com-

mand.

Sample Command:

02 03 00 00 08

Delay 1 ms, monitor SINT, or poll E2DREQ

Filter Stop - 0x09

This command disables the digital filter. Measure-

ment data output stops immediately after this com-

mand is issued. No data words are required for this

configuration command.

Sample Command:

02 03 00 00 09

Delay 1 ms, monitor SINT, or poll E2DREQ
