  @Summary
    This is the generated driver implementation file for the TMR4 driver using PIC10 / PIC12 / PIC16 / PIC18 MCUs

  @Description
    This source file provides APIs for TMR4.
    Generation Information :
        Product Revision  :  PIC10 / PIC12 / PIC16 / PIC18 MCUs - 1.76
        Device            :  PIC16F1769
        Driver Version    :  2.11
    The generated drivers are tested against the following:
        Compiler          :  XC8 2.00 
        MPLAB 	          :  MPLAB X 5.10
