Microcontrollers Debugger Manual
– The part did not start the monitor mode security check on reset. Signals to force
monitor mode may be incorrect.
– The baud rate specified was incorrect.
– The processor was not reset properly. Check the
Target Hardware Type
and, if
you are connecting to a class II board, check the
MON08 cable communication
connections type
in the
Advanced Settings
dialog box.
•
3 – Device signaled monitor mode with a break:
Once the processor has properly received the 8 bytes from the PC software to
complete its security check, it transmits a break character to the PC signaling entry
into monitor mode. This break character is sent regardless of whether the security
check was successfully passed. If a break is not received from the processor, this flag
reads ‘N’. Reasons for this include:
– The baud rate specified was incorrect.
– 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.
•
4 – Device entered monitor mode:
Once the software has received, or failed to receive, a break from the processor, it
attempts to communicate with the monitor running on the M68HC08 processor. It
tries to read the monitor version number by issuing a monitor mode read. If the
processor fails to respond properly to this command, this flag reads ‘N’.
•
5 – Reset was Power-On Reset:
If the device properly entered monitor mode (4), the software reads the reset status
register (RSR). This read does not affect the security sequence, and occurs purely for
diagnostic reasons. The RSR indicates the conditions under which the processor
underwent the last reset. For the software to pass the security check properly, it
MUST first cause the processor to undergo a Power-On Reset. The software reads
the RSR to determine if the last reset was indeed caused by power-on. The result of
the RSR read is indicated in parentheses after the flag value. If the highest bit is not
set then the reset was not a power-on reset, and the flag reads ‘N’. Reasons for this
include:
– 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.
