This is the interrupt service routine for the Counter16 usermodule written
in C. The boot.tpl has been modified to jump to this ISR every terminal
count. The related #pragma above is necessary for the boot.asm file to jump
to it. Every time a terminal count is reached the DAC will get the next
value from the sinTable.
/* Step 1: Get BYTE data from the ADC
*/
/* Is new data available from the ADC? */
