+// @Description   This is the initialization function of the Timer 21 
+//                function library. It is assumed that the SFRs used by this 
+//                library are in their reset state. 
+//                
+//                The following SFRs and SFR fields will be initialized:
+//                T21_RC2H/RC2L     - reload/capture timer 21 register
+//                T21_T2H/T2L     -  timer 21 register
+//                EX2           - timer 21 interrupt enable
+//                T21_T2MOD         - timer 21 mode register
+//                CP/RL2        - Capture/Reload select
+//                EXEN2         - External enable control
+//                TR2           - Timer21 run control
