After calculating the code required for the D/A data, combine it with the code

required for the channel number.

For example, to set the output on channel 3 to 11.890625mA:

CODE = 11.890625mA - 4 / 16 * 4095 = 2020

The digital code for 2020 is 0111 1110 0100.

To this, you would add the value for channel 3 (0011) as the upper nibble for the

second register.

The end result is 0011 0111 1110 0100.

This is written to the registers as:

BASE + 0: 228 (or E4 hex)

BASE + 1: 55 (or 37 hex)

1 2 ... 8 9 10 11 12 13 14 15 16
