A typical parallel loading session would follow this procedure. First, set the contents of the MCON
register with the correct range and partition only if using expanded programming cycles. Next, the
encryption registers can be loaded to enable encryption of the program/data memory (not required). Then,
program the DS5000(T) using either normal or expanded program cycles and check the memory contents
using Verify cycles. The last operation would be to turn on the security lock feature by either a Security
Set cycle or by explicitly writing to the MCON register and setting MCON.0 to a 1.

ADDITIONAL INFORMATION
Refer to the Secure Microcontroller User’s Guide for a complete description for all operational aspects of
the DS5000(T).
DEVELOPMENT SUPPORT
The DS89C450-K00 evaluation kit (www.maxim-ic.com/DS89C450evkit) can be used to develop and
test user code. It allows the user to download Intel hex-formatted code to the DS5000(T) from a PC.
Refer to the Secure Microcontroller User’s Guide for more information.
