/* This code currently allows for:
MSPGCC - the GNU tools for the MSP430
Quadravox AQ430
IAR Version 1 (old syntax)
IAR Versions 2, 3, 4, 5 (new syntax)
Rowley Crossworks
Code Composer Essentials
These macros allow us to define interrupt routines for all
compilers with a common syntax:
ISR(<interrupt>, <routine name>)
{
}
e.g.
ISR(ADC12, adc_service_routine)
{
ADC12CTL0 &= ~ENC;
ADC12CTL0 |= ENC;
}
