The characteristics of Digital/Analog/Frequency pins are PLUS+1
can be digital, analog or frequency. Inputs can be pulled to 5 Vdc, pulled to ground, pulled to 2.5 Vdc, or
no pull-up/pull-down.

Frequency (Hz)
Period (0.1 µsec)
Channel to channel phase shift (paired inputs . . . ) (0.1 ms).
PWM duty cycle (0.01%)—Duty cycle measurement only valid up to 5 kHz (FreqIN).
Edge count.
Quadrature count (paired inputs driven from a quadrature encoder).
No pull down/ pull up is standard with pull up or pull down programmable; failure modes are detectable.
The controller may re-boot under some high frequency load conditions above 10 kHz.
