  @Summary
    This is the generated driver implementation file for the EUSART1 driver using PIC10 / PIC12 / PIC16 / PIC18 MCUs

  @Description
    This source file provides APIs for EUSART1.
    Generation Information :
        Product Revision  :  PIC10 / PIC12 / PIC16 / PIC18 MCUs - 1.81.7
        Device            :  PIC18F46K22
        Driver Version    :  2.1.1
    The generated drivers are tested against the following:
        Compiler          :  XC8 2.31 and above
        MPLAB             :  MPLAB X 5.45
