2.12.1. User Interrupt Input (UINT) (J12)

The UINT1 (Input 12) and UINT2 (Input 13) ± inputs are used for the hardware Encoder Capture feature. The
delay time through the high-speed opto devices is 50 nsec (typical). The high-speed user interrupt inputs are
scaled for 5 VDC input. Using a higher input voltage requires an external series resistor to limit the current to
15 mA.
