E.1 Initialization Programs
M68HC16 Z SERIES
USER’S MANUAL
This section contains basic initialization programs and several programming exercises
using different M68HC16 Z-series modules. The purpose of these exercises is to pro-
vide the designer and programmer with a means to shorten design time. All of the pro-
grams were written to run on the M68HC16Z1EVB evaluation board. Refer to the
M68HC16Z1EVB Evaluation Board User’s Manual (M68HC16Z1EVB/D) for further in-
formation.
The following initialization routines accompany the programming examples used in
this manual. For information on assembler commands and directives, refer to the
M68HC16Z1EVB Evaluation Board User’s Manual (M68HC16Z1EVB/D).
• EQUATES.ASM — This program lists of all the MC68HC16 registers equated to
• ORG00000.ASM — This program consists of five lines of code that set the reset
• ORG00008.ASM — This program initializes the interrupt/exception vectors
• INITSYS.ASM — This program consists of ten to twelve lines of code that initial-
• INITRAM.ASM — This program initializes the 1-Kbyte internal SRAM at $10000,
• INITSCI.ASM — This program initializes the SCI to transmit and receive at 9600
their memory address. This allows programmers to use the register name in their
programs, and then the assembler selects the correct memory address for that
register.
vector information into the proper locations.
($0008 – $01FE). If an interrupt occurs requiring the use of any of these vectors,
program flow continues at the label “BDM”. The programmer must add code at
the label location to put the program running on the EVB16 into background de-
bug mode or some other appropriate routine.

INITIALIZATION AND PROGRAMMING EXAMPLES
These programs will also work on the Modular Evaluation Board
(MEVB) using a microcontroller personality board for the appropriate
Z-series derivative. See
for more information on the MEVB.
