Looking over the data sheet for the chip, and I think I got some of the commands, but its the memory registers to use for my simple logic that eludes me. It only uses 2 inputs and 5 outputs, one leading to the relay to the output and 3 LEDs. How would I go about finding what memory registers to use in my program?
Circuit Logic
Upper + Lower = 1; Operation = 1; Warn = 0; Refill = 0
Upper = 0; Lower = 1; Operation = 1; Warn = 1; Refill = 0
Upper = 0; Lower = 0; Operation = 0; Warn = Flashing; Refill =1
