## Hardware

Platform Intel MCS-51 (8051): The Intel MCS-51 (commonly termed 8051) is an internally Harvard architecture, complex instruction set computer (CISC) instruction set, single chip microcontroller (uC) series developed by Intel in 1980 for use in embedded systems.

Microcontroller | N79E855
Frequency | 22MHz
Flash | 16KB
RAM | 512B
Vendor | Nuvoton

## Configuration

Please use `n79e855` ID for board option in “platformio.ini” (Project Configuration File):

    [env:n79e855]
    platform = intel_mcs51
    board = n79e855

You can override default Generic N79E855 settings per build environment using `board_***` option, where `***` is a JSON object path from board manifest n79e855.json. For example, `board_build.mcu`, `board_build.f_cpu`, etc.

    [env:n79e855]
    platform = intel_mcs51
    board = n79e855

    ; change microcontroller
    board_build.mcu = n79e855

    ; change MCU frequency
    board_build.f_cpu = 22118400L

## Debugging

PIO Unified Debugger currently does not support Generic N79E855 board.
