These three timers can be programmed as a timer element or as a counter element. Timer 0 and 1 are each
connected to two external pins (TMRIN0, TMROUT0, TMRIN1, TMROUT1), which can be used to count or time
external events, or used to generate a variable-duty-cycle waveforms. Timer 2 is not connected any external pins. It
can be used as a prescaler to Timer 0 and Timer 1 or as a DMA request source.
These bit definitions for timer 0 are the same as those of register 5Eh for timer 1.
