an external input clock. TB0MOD<TBCPM1:0> is set to “11.” This setting allows a count value of
the 16-bit up-counter UC to be taken into the capture register (TB0CP0) upon rising of a timer

between TB0CP0 and TB0CP1 is 100, the frequency is 100 / 0.5 s = 200 Hz.
Frequency
The frequency of an external clock can be measured by using the capture function.
To measure frequency, another 16-bit timer is used in combination with the 16-bit event counter
The TB0IN pin input is selected as the TMRB0 count clock to perform the count operation using
A frequency is then obtained from the difference between TB0CP0 and TB0CP1 based on the
For example, if the set width of TB7FF0 level “1” of the 16-bit timer is 0.5 s and if the difference
