// @Description   This is the initialization function of the Timer 0/1 
//                function library. It is assumed that the SFRs used by this 
//                library are in their reset state. 
//                
//                The following SFR fields will be initialized for both 
//                timers 0 and 1:
//                T0M            - Timer 0 mode
//                T1M            - Timer 1 mode
//                GATE0/GATE1    - gating control
//                TLx, THx       - timer low/high registers
//                ETx            - interrupt enable
//                TRx            - timer run control (this is the final
