• Trigger 2: Timed Interrupt. This provides a real-time clock and
delay timer function. During an injection, this interrupt program
performs Flow Rate and Volume Limit calculations. This interrupt
is not externally triggered, but driven from the time divided clock
generator.
Test Decoder This 4-16 channel decoder (U2) provides Reset pulses for Watchdog
1, and controls timing of the buzzer.
Test Section The circuit surrounding U17 and U18 is for in-house testing.
