+  EPWM1 Generated Driver File
+
+  @Company
+    Microchip Technology Inc.
+
+  @File Name
+    epwm1.c
+
+  @Summary
+    This is the generated driver implementation file for the EPWM1 driver using PIC10 / PIC12 / PIC16 / PIC18 MCUs
+
+  @Description
+    This source file provides implementations for driver APIs for EPWM1.
+    Generation Information :
+        Product Revision  :  PIC10 / PIC12 / PIC16 / PIC18 MCUs - 1.81.8
+        Device            :  PIC18F97J60
+        Driver Version    :  2.01
