This routine runs but it runs fast the crystal is 12Mhz and the configuration

*FILE NAME:    msecWait.c

*NOTE:Since the counter counts up it is necessarey to *     subtract the nuber of counts/millsecnd from the *     maximum count for Counter 0 which is 0xFC65) *     seperated into bytes(unsigned char) hiByte =
*     0xFC and lowByte = 0x65.
*
*DESCRIPTION:  Delays for the input argument number *              of miliseconds
*
*INPUTS: Requested number of miliSeconds (0.001 *        Seconds) to delay
*
*OUTPUTS:        processor is on hold for the proscribed *          number of milliseconds
