Once out of reset, the MCU waits for the host to send eight security
bytes. (See
sends a break signal (10 consecutive logic 0s) to the host, indicating that
it is ready to receive a command.
In monitor mode, the MCU uses different vectors for reset, SWI, and
break interrupt than those for user mode. The alternate vectors are in the
$FE page instead of the $FF page and allow code execution from the
internal monitor firmware instead of user code.
The COP module is disabled in monitor mode as long as V
applied to either the IRQ pin or the RST pin.
