C DEVELOPMENT SUPPORT
C.1 M68HC11EVB — Evaluation Board
Refer to the M68HC11EVB Evaluation Board User’s Manual (M68HC11EVB/D1). The
Evaluation Board (EVB) is a low cost tool for debugging and evaluating M68HC11
MCU-based target system equipment. The EVB is designed to operate in either the
debugging or evaluation mode of operation.
C.1.1 EVB Features
• A low cost means of debugging user-assembled code and evaluating target sys-
tems incorporating M68HC11 MCUs
• One-line assembler/disassembler
• Host computer downloading capability
• M68HC11 MCU-based debugging/evaluating circuitry
• MC68HC24 Port Replacement Unit (PRU)-based MCU l/O expansion circuitry
• MC6850 Asynchronous Communications Interface Adaptor (AClA)-based termi-
nal l/O port circuitry
• RS-232C compatible terminal/host computer l/O ports

C.2 M68HC11EVBU — Universal Evaluation Board
Refer to M68HC11EVBU Universal Evaluation Board User’s Manual
(M68HC11EVBU/AD1). The EVBU is a low cost development tool for debugging and
evaluation of MC68HC11A8, E9, 7E9, and 8E2 MCUs. The EVBU was designed along
with a monitor/debugging program called BUFFALO (Bit User Fast Friendly Aid to Log-
ical Operations). This monitor program is contained in MCU ROM. The debugging/
evaluation operation allows the user to debug user code under control of the BUFFA-
LO monitor program.
C.2.1 EVBU Features
• A low-cost means of debugging user assembled code and evaluating
MC68HC11A8, E9, 7E9, and 8E2 MCU devices
• BUFFALO monitor in ROM or PCBUG11 software working through boot mode
• One-line assembler/disassembler
• Program downloading capability
• M68HC11-based debugging/evaluating circuitry
• RS-232C compatible terminal l/O port
• Wire-wrap area for custom interfacing
• Single (+5 Vdc) input power source requirements
