SERIAL CONTROL INPUT
The SERIAL_INPUT signal is used to set some system flags using a single-byte control
scheme. With the serial interface operating at 115200 baud, 8n1 configuration. The default values
correspond to the all-zeroes case.
If the serial input is held high for more than five seconds without receiving additional bytes, the
system will enter debug mode. If the input is held low or left floating, the system will continue
operating with the previously set values, or if none were set, the default configuration. This aspect of
system configuration is volatile, not being saved through power cycles.
DEBUG MODE
When in debug mode, the system is turned on using an internal test pattern generator. Video inputs are
ignored. The test pattern generator cycles through the four supported resolutions, resulting in an image
like this one:
