/*
 *  The bits in the pin mode macros are as follows:
 *  The lower 8 bits of the macro refer to the pin, offset by 1, to match
 *  driverlib pin defines.  For example, UART2CC32XX_PIN_01_UART1_TX & 0xff = 0,
 *  which equals PIN_01 in driverlib pin.h.  By matching the PIN_xx defines in
 *  driverlib pin.h, we can pass the pin directly to the driverlib functions.
 *  The upper 8 bits of the macro correspond to the pin mux confg mode
 *  value for the pin to operate in the UART mode.  For example, pin 1 is
 *  configured with mode 7 to operate as UART1 TX.
