This section describes the monitor read-only memory (ROM). The
monitor ROM (MON) allows complete testing of the microcontroller unit
(MCU) through a 2-wire interface with a host computer.
Features of the monitor ROM include:
•
•
•
•
Normal user-mode pin functionality
Standard mark/space non-return-to-zero (NRZ) communication
with host computer
9600 baud communication with host computer
Execution of code in random-access memory (RAM) or ROM
