4.2 User System Interface Board Circuits
Some signals from the optional user system interface board are connected to a switch and a pull-up
resistor. When using the user system interface board, determine the values of the pull-up resistors
with reference to section 4.1, User System Interface Circuits, and the circuit diagrams in this
section.
Figures 4.13 through 4.18 show user system interface board circuits.
