loaded into the capture register TB0CP0H/L at the rise edge of the timer flip-flop
TA1FF of 8-bit timers (TMRA1), and into TB0CP1H/L at its fall edge.

to 0.5 s and the difference between the values in TB1CP0H/L and TB1CP1H/L is
100, the frequency is 100 ÷ 0.5 s = 200 Hz.
The frequency of the external clock can be measured in this mode. Frequency is
TMRA23 is used to setting of measurement time by inversion TA3FF.
Counter clock in TMRB0 select TB1IN0 pin input, and count by external clock
The frequency is calculated by difference between the loaded values in
For example, if the value for the level 1 width of TA3FF of the 8-bit timer is set
