4.4.3 Digital inputs - X3
Digital inputs DIN0 to DIN3 can be used as high speed position latches. The fast position
inputs are routed through a programmable cross-point switch which allows any input to cause
the position of any combination of axes to be captured (by the hardware) within 1µs. Special
MintMT keywords (beginning with the letters FAST...) allow specific functions to be performed
as a result of fast position inputs becoming active.
Note: Digital inputs DIN0 to DIN3 are particularly sensitive to noise, so inputs must use
shielded twisted pair cable.
