What is Custom HH:MM:SS Down Timer Program about?

This program describes a down timer that counts down past zero to negative times. It can be preset with an initial time (X) and an event time (Y) that will trigger a relay output. The preset and event time are stored in an MRP chip with no battery backup. The timer displays hours, minutes, and seconds and the relay output will also turn on at 00:00:00 at 1hz. The timer can be preset or reset by a momentary input and uses a 68HC05C8 processor with a 228/406 target display at 1200 baud serial communication.
