The OnCE commands can be classified as:
A typical debug environment consists of a target system in which the
MCU resides in the user-defined hardware.
The external command controller acts as the medium between the MCU
target system and a host computer. The external command controller
circuit acts as a serial debug port driver and host computer command
interpreter. The controller issues commands based on the host
computer inputs from a user interface program which communicates
with the user.
