HC08 P&E Multilink/Cyclone Pro Connection
Connection Procedure
374 Microcontrollers Debugger Manual
– The processor did not power all the way down because power was being supplied
to the processor through either the port pins, IRQ line, RESET line, or power
pins.
– The voltage driven on the power pin of the processor did not go below 0.1 volts.
– The processor was not reset properly. Check the Target Hardware Type. If you
are connecting to a class II board, check the MON08 cable communication
connections type in the Advanced Settings dialog box.
• 6 – ROM is accessible (un-secured):
If the device properly entered monitor mode (4), the software reads locations $FFF6-
$FFFF to determine if the processor passes the security check. Memory locations
which are invalid or protected read back from the device as $AD. If all bytes from
$FFF6-$FFFF read a value of $AD, it is assumed the device is secure, and the flag
value is an ‘N’. If all flags 0-5 register a value of ‘Y’ and flag 6 registers a value of
‘N,’ then the reset process has occurred correctly except that the security code used
to pass security was incorrect. Specify the correct security code and try again, or
IGNORE the security failure and erase the device. Once you erase a secured device,
you must exit the software and restart it in order to pass security.

Device Option
The Device option in the MultilinkCyclonePro menu allows the user to select the
particular Freescale processor that they wish to use. When choosing Device from the
MultilinkCyclonePro menu, extended menus open that allow you to select the family (e.g.
AB Family), and device type of the MCU that you are using.
