MCP42XXEV Evaluation Board User’s Guide
Double clicking on the WriteWiper0 User SPI Script will load the script details.
Figure 2-10 shows what the values mean in the Script Details. These values are hex
numbers.
The first value (02h), is the number of bytes that will be written. The second byte is a
data byte and contains the device register address, the Device command, and the two
Most Significant bits (MSb) of the write data. The third byte is the 2nd data byte and
contains the remaining 8 bits of the write data.
Number of Bytes that will
be written
Data Byte #1
(Device Register Address +
Command + Data bit “D8”
Data Byte #2
(Write Data “D7:D0”
