Sample Command:

Write IIR1 coefficients 0x84BC9D, 0x7DA1B1,

0x825E4F, and IIR2 coefficients 0x83694F,

0x3CAD5F, 0x3E5104, 0x835DF8, 0x3E5104.

Write ROM Coefficients - 0x04

This EEPROM command selects the on-chip coef-

ficients for the FIR1, FIR2, IIR 1st order, and IIR

2nd order filters for use by the digital filter. One

data word is required to select which internal coef-

ficient sets to use. See “Filter Coefficient Selec-

tion” on page 41 for information about selecting

on-chip FIR and IIR coefficient sets.

Sample Command:

Select IIR1 and IIR2 3 Hz @ 500 SPS low-cut co-

efficients, with FIR1 and FIR2 linear phase high-

cut coefficients. Data word 0x002200.

Write TBS Data - 0x05

This EEPROM command writes a custom data set

for the test bit stream (TBS) generator. This com-

mand, along with the ability to program the test bit

stream generator interpolation and clock rate, can

create custom frequency test signals.

The first data word sets the number of TBS data to

be written and the remaining data words are the

TBS data values. See “Test Bit Stream Generator”

on page 64 for information about using custom test

bit stream data sets.

Table 5. EEPROM Boot Configuration Commands

(DATA) indicates multiple words of this type are to be written.
