OUT3N and RAW_DATA (Test Register is Set to 0x19) for BPSK Pattern
The following table summarizes key test codes for configuring the Test[6:0] bit field (Sector0-0x3A.[6:0]) to route
internal key signals to monitor for adjustment of the above parameters. While the meanings of such signals are
explained in the accompanying "Meaning of Key Test Signal" table.
