Status In/Status Out/Pulse Outputs
The MIO2 board provides four (maximum) digital I/O channels that can be individually software-
configured as status inputs, status outputs or pulse outputs. Each of the four channels is identical, and
is implemented using a comparator for detecting the state of an (status) input, and an n-channel
MOSFET to provide an open drain status output driver. Pulse outputs are provided by simply driving
the status output on and off at the required pulse output rate in an interrupt driven software routine.
The channels on the MIO2 board are identical to those on the mainboard.
