.
This sets the time delay for when the display should start receiving WDT reset commands, via the
internal UART, after power is applied to the Compute Module.
This timer's value should be set high enough to include time for the operating system to fully load, on the
Compute Module, and for the periodic reset commands to begin sending to the display.

Period Time
For use only when the

This sets the maximum amount of time within which the display must receive WDT reset commands from
the Compute Module, via the internal UART. If two consecutive reset commands are missed, the display
will restart the Compute Module.
This timer’s value should be set high enough to ensure that any software running on the Compute Module
will be able to send the periodic reset command to the display, even under heavy load conditions.
