* Side Effects: TMR0 for PIC18 is configured for calculating

*
* Overview: This function will configure the UART for use at

* Note: The timer interrupt is enabled causing the timer
* roll over calculations. Interrupts are required
* to be enabled in order to extend the timer to
* 4 bytes in PIC18. PIC24/dsPIC version do not
* enable or require interrupts
