This section describes the monitor ROM (MON) and the monitor mode
entry methods. The monitor ROM allows complete testing of the MCU
through a single-wire interface with a host computer. Monitor mode entry
can be achieved without use of the higher test voltage, V
vector addresses $FFFE and $FFFF are blank, thus reducing the
hardware requirements for in-circuit programming.
Features of the monitor ROM include:
