On success, the return code is “+” followed by the
read data. On failure, the return code is “-”.
• Some commands are used only during firmware
development. Firmware command “S” simulates a
dummy device using on-chip memory, instead of
device registers, used during firmware development.
Firmware command “~” prints a diagnostic trace
dump used during firmware development. Firmware
commands “1” and “2” perform HDCP link authen-
tication-check operations, used during firmware
development. In normal operation, these operations
are triggered by the VSYNC interrupt handler.
