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 flag is set to “1”at reset.
In these modes, the count type can be selected by the count-type
select bit (bit 4 of the timer Bi mode register). When this bit = “1”, the
free-run type is selected; in this case, even when a valid edge is in-
put to pin TBiIN, the contents of the counter will not be cleared to
“000016”, and counting will continue. However, when a valid edge is
input, an interrupt-requesting signal will be generated.
