GENERAL DESCRIPTION

The EVBU provides a low cost tool for debugging/evaluation of MC68HC11A8, E9, 711E9,
811A8, and 811E2 MCUs. The MC68HC11 MCU device is an advanced single-chip MCU with
on-chip memory and peripheral functions. Refer to the MC68HC11 MCU data sheet for
additional device information. The EVBU and a monitor/debugging program called BUFFALO
(Bit User Fast Friendly Aid to Logical Operations) demonstrate the capabilities of this MCU. The
monitor program is contained in MCU ROM. The debugging/evaluation operation lets you debug
user code under control of the BUFFALO monitor program.
