BLOCK DIAGRAM AND DESCRIPTION
The EVAL-ADGS1412SDZ software is organized so that it
appears similar to the functional block diagram shown in the
data sheet. In this way, it is easy to correlate the functions on the
EVAL-ADGS1412SDZ board with the description in the data
sheets. A full description of each block, register, and settings is
given in the ADGS1412 data sheet.
EVAL-ADGS1412SDZ User Guide
Some of the blocks and their functions are described here as
they pertain to the evaluation board. The full screen block
diagram, shown in Figure 4, describes the functionality of each
block.
