User Options

User options include 2 LED’s, and 2 pushbutton switches. Each user option may be enabled
individually using the USER option header. When the appropriate USER option jumper is
installed, the associated user option is enabled. Removing a jumper disables the associated
user option.

Switches

Two push button switches provide momentary, active low, input to the MCU for user
applications. Pressing a switch provides a momentary low logic level input tot the MCU. SW1
and SW2 provide input to MCUI/O ports PE0 and PP5 respectively.
