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 host computer. This mode is also
used for programming and erasing of FLASH memory in the MCU.
Monitor mode entry can be achieved without use of the higher voltage,
V
thus reducing the hardware requirements for in-circuit programming.
