T2PS[2:0]: Prescaler select bit:
T2PS = 000 – timer 2 is clocked with the oscillator frequency.
T2PS = 001 – timer 2 is clocked with 1/2 of the oscillator frequency.
T2PS = 010 – timer 2 is clocked with 1/4 of the oscillator frequency.
T2PS = 011 – timer 2 is clocked with 1/6 of the oscillator frequency.
T2PS = 100 – timer 2 is clocked with 1/8 of the oscillator frequency.
T2PS = 101 – timer 2 is clocked with 1/12 of the oscillator frequency.
T2PS = 110 – timer 2 is clocked with 1/24 of the oscillator frequency.
T2R[1:0]: Timer 2 reload mode selection
T2R[1:0] = 0X – Reload disabled
T2R[1:0] = 10 – Mode 0: Auto Reload
T2R[1:0] = 11 – Mode 1: T2EX Falling Edge Reload
T2I[1:0]: Timer 2 input selection
T2I[1:0] = 00 – Timer 2 stop
T2I[1:0] = 01 – Input frequency from prescaler (T2PS[2:0])
T2I[1:0] = 10 – Timer 2 is incremented by external signal at pin T2
T2I[1:0] = 11 – internal clock input is gated to the Timer 2
