;
; Hardware:   MSP430-P1121-E
;             POWER SUPPLY +9VDC,  MCU MSP430F1121 / 32768 Hz crystall
;             LED at P1.0
;             
; Date:       14.04.2002
;
; This software is provided "as is" for evaluation of our MSP430-P1121
; development board. You are free to use this code in your projects, but 
; without warranty of any kind. If you can't understand how and what the 
; code does it's better to start by learning the MSP430 datasheets, and 
; assembly language, but don't call OLIMEX with questions regarding this 
; software. OLIMEX will not teach you how to write assembly language nor 
; how to use MSP430 peripherials, there is plenty of datasheets about them.
