  @File Name
    tmr0.c

  @Summary
    This is the generated driver implementation file for the TMR0 driver using PIC10 / PIC12 / PIC16 / PIC18 MCUs

  @Description
    This source file provides APIs for TMR0.
    Generation Information :
        Product Revision  :  PIC10 / PIC12 / PIC16 / PIC18 MCUs - 1.65.2
        Device            :  PIC16F1579
        Driver Version    :  2.01
    The generated drivers are tested against the following:
        Compiler          :  XC8 1.45
        MPLAB             :  MPLAB X 4.15
