TARGET MCU SECURITY BYTES

Power Down ICS, Ask the user to power cycle their board, Power UP ICS
This option will work for many ICS boards as well, but relies on the fact that
while the ICS is powered off, it will hold the target in reset until it is powered
up itself and has configured the MON08 configuration pins. The sequence of
events in this mode is:
One of the steps that is necessary to properly bypass security is to provide the
proper security code for the information that is programmed into the part. This
holds true even when the part is blank.
The security code consists of the 8 values which are currently stored in flash
locations $FFF6 - $FFFD of the processor. The PROG08SZ flash
programming software continually records any changes to these security bytes
and stores them in the file SECURITY.INI. The information in this file is
shared with P&E's In-Circuit Debugger and In-Circuit Simulator software, and
will appear in the dialog box. This allows the user to specify which security
code to use to pass security.
1. Software automatically powers down the ICS.
2. Software asks the user to power cycle their board as follows:
3. Software automatically powers up the ICS, which configures the
processors MON08 configuration pins.
