RC2L/H. The underflow condition sets the TF2 flag and causes FFFF
into the T2L/H registers. A fresh down counting sequence is started and the timer/
counter counts down as in the previous counting sequence.
In this mode, bit EXF2 toggles whenever an overflow or an underflow condition is
detected. This flag, however, does not generate an interrupt request.
Note: In counter mode, if the reload via T2EX and the count clock T2 are detected
