Revision:
20:26b1a4570f4b
Parent:
17:af1f2416dd26 
The following changes were made:

1.) Modified udelay() function for generating more accurate smaller usec delays

2.) Implemented the irq_enable and irq_disable functions

3.) Removed the confusion b/w application created peripheral object and interrupt specific object

4.) Created PWM extra init structure and added PWM pin as it's member for multiplatform project compatibility

5.) Added a module for timer and its related header file
