11.2 16-bit Timer / Counter Mode
The Timer register is being run with all 16 bits. A 16-bit
timer/counter register T0, T1 are incremented from 0000H
until it matches TDR0, TDR1 and then resets to 0000H.
The match output generates Timer 0 interrupt.
The clock source of the Timer 0 is selected either internal
or external clock by bit T0SL1, T0SL0.
Even if the Timer 0 (including the Timer 1) is used as a 16-
bit timer, the Timer 2 and Timer 3 can still be used as either
two 8-bit timer or one 16-bit timer by setting the TM2. Re-
versely, even if the Timer 2 (including the Timer 3) is used
as a 16-bit timer, the Timer 0 and Timer 1 can still be used
as 8-bit timer independently.
