This section describes the monitor read-only memory (MON). The
monitor ROM allows complete testing of the microcontroller unit (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 hardware
requirements for in-circuit programming.
