5.3.7 SPI 1 Commands

The SPI 1 commands are used to write and read the

decimation engine registers, write digital filter co-

efficients, write test bit stream generator data, and

enable or disable the digital filters. All configura-

tion of the decimation engine in coprocessor mode

is performed using these commands. Available

SPI 1 to decimation engine commands and their re-

quired register values are listed in Figure 20.
