1 – Device echoed some security bytes:
2 – Device echoed all security bytes:
3 – Device signaled monitor mode with a break:
analyzing the reset of the status bits.
The monitor resident in a 68HC08 device automatically echoes every
incoming character when it is in monitor mode. A valid character
transmitted from the PC should be echoed once by the loopback circuitry
on the board and once by the monitor of the target processor itself. This
status indicates whether or not the second echoed character from the
monitor response was received when one of the security bytes was
transmitted. If the status is ‘N’, which indicates that the character was not
received, or not received properly, it is most likely due to one of the
following reasons:
If this status bit responded with an ‘N’, you must correct this before
analyzing the reset of the status bits.
In order to pass security, the software must send 8 security bytes to the
processor. The processor should echo each of these eight bytes twice. If all
8 bytes did not get the proper two-byte echo, this flag will be ‘N’. Reasons
for this include:
Once the processor has properly received the 8 bytes from the PC software
to complete its security check, it should transmit a break character to the
PC signaling entry into monitor mode. This break should be sent regardless
of whether the security check was successfully passed. If a break was not
received from the processor, this flag will be ‘N’. Reasons for this include:

1. The baud rate specified was incorrect.
2. The part did not start the monitor mode security check on reset.
Signals to force monitor mode may be incorrect.
3. No Power to the ICS.

Signals to force monitor mode may be incorrect.
2. The baud rate specified was incorrect.
3. 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.
