When timer Bi is read, the contents of the reload register is read.
Note that in this mode, the interval between the fall of the TBiIN pin
input signal to the next rise or from the rise to the next fall must be at
least two cycles of the timer count source.
Timer Bi overflow flag which is bit 5 of timer Bi mode register is set to
“1” when the timer Bi counter reaches 000016, which indicates that a
pulse width or pulse period is longer than that which can be mea-
sured by a 16-bit length.
This flag is cleared by writing data to the corresponding timer Bi
mode register. This bit is set to “1”at reset.
