+// Function to setup timer on AVR
+//
+// Calling Sequence
+// u8AVRTimerSetups(timer, prescalar)
+//
+// Parameters
+// timer: timer to be set up (0,1,2)
+// prescalar: prescalar to be used for timer (0-7)
+// ***Refer datasheet for more description about timer
+//
+// Description
+// This function sets prescalr for timers. 'timer' decides which of the
+// three (0,1,2) timers available to be used. The 'prescalar' is needed for
+// deciding timer clock. Select appropriate prescalar depending on MCU clock
+// and requirement.
