Revision:
20:4951ea6abee5
Parent:

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

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