PRBS Register Writes for Custom Setup
If the user is implementing the test without using the TI EVMs or GUI software the following register writes
must be made in place of the previous steps to achieve the correct test setup. The registers in the DAC
are arranged according to page number and addresses. The page number indicates to which portion of
the DAC the registers are associated. The page number is indicated in the low-level view by the first digit
in the address field.
