Where A0 = Status of input A, channel 0 - bit = 1 when input is on

B0 = Status of input B, channel 0 - bit = 1 when input is on

Z0 = Status of input Z, channel 0 - bit = 1 when input is on

G0 = Status of input G, channel 0 - bit = 1 when input is on

A1= Status of input A, channel 1 - bit = 1 when input is on

B1 = Status of input B, channel 1 - bit = 1 when input is on

Z1 = Status of input Z, channel 1 - bit = 1 when input is on

G1 = Status of input G, channel 1 - bit = 1 when input is on

C0 = Cal 0 - when bit is set, counter 0 has been calibrated (reset by CalReset)

C1 = Cal 1 - when bit is set, counter 1 has been calibrated (reset by CalReset)

S0 = Stored 0 - when bit is set, counter 0 value has been saved in Store 0 (reset by

StoreReset)

S1 = Stored 1 - when bit is set, counter 1 value has been saved in Store 0 (reset by

StoreReset)

Once a store has occurs, L0 and L1 are on until cleared by StoreReset (counter word bit 14)

PR0 = Preset 0 reached - when bit is set, counter 0 has reached value of preset (reset by

PresetReset)

PR1 = Preset 1 reached - when bit is set, counter 1 has reached value of preset (reset by

PresetReset)

CT DIR 0 = Increase/Decrease counter value for counter 0: set to 0 at startup. 0 = last pulse

counter value; 1 = last pulse increased counter value

CT DIR 1 = Increase/Decrease counter value for counter 1: set to 0 at startup. 0 = last pulse
