12  * 25/2/2013 Rev.01 Includes functions for UART0 ONLY. Configured to function on PTA1 and PTA2.
13  * Configured for 38400 8 N 1. Configured to run from MCGFLLCLK @ 20.97152MHz
14  * Uses Interrupt for RX, does NOT use interrupt for TX.
15  * 7/3/2013 Rev.02 Modified UART0 IRQ to use a Callback if one is registered.
16  * 12/3/2013 Rev.03 Enabled dynamic baud rate setting.
17  * 5/2/2014 Rev.04 Added code for UART1 and UART2. Still static pin mappings.

26  * ***NB*** This file is intended for use with a new "Bareboard" project (with no rapid-development) in Code Warrior.
27  * If this is not the case, you MUST ensure that an appropriate entry of "UART0_IRQHandler" exists in entry 28
28  * (address 0x00000070) of the VectorTable.
29  *
30  * Appropriate entries for the interrupt handler exist in the vector table contained in the generated
31  * kinetis_sysinit.c file
