<h1>Introduction</h1>
|
| 9 |
|
|
|
| 10 |
|
|
The openMSP430 is a synthesizable 16bit microcontroller core written in Verilog. It is compatible with Texas Instruments' MSP430 microcontroller family and can execute the code generated by an MSP430 toolchain in a cycle accurate way.
|

The core comes with some peripherals (16x16 Hardware Multiplier, GPIO, TimerA, generic templates) and a Serial Debug Interface for in-system software development.
