| 
 | |
|   @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 - 1.81.8
 | |
|         Device            :  PIC18F26K83
 | |
|         Driver Version    :  3.10
