TB5RG1 is set to the sum of the TB5CPO value (c) and the one-shot pulse width (p), (c + p),
by generating the INT0 interrupt. TB5RG1 change must be completed before the next
match. TB5FF0 is enabled to reverse when UC5 matches with TB5RG1, and is disabled by
generating the INTTB5 interrupt.
If a delay is not required, TB5FF0 is reversed when data is taken into TB5CP0, and
Frequency measurement
The frequency of an external clock can be measured by using the capture function.
To measure frequency, another 16-bit timer (TMRB0) is used in combination with the
16-bit event counter mode. As an example, we explain with TMRB3 and TMRB8.
TB8OUT of the 16-bit timer TMRB8 is used to specify the measurement time.
The TB3IN0 pin input is selected as the TMRB3 count clock to perform the count
operation using an external input clock. TB3MOD<TB3CPM1:0> is set to “11.” This
setting allows a count value of the 16-bit up-counter UC3 to be taken into the capture
register (TB3CP0) upon rising of a timer flip-flop output (TB8OUT) of the 16-bit timer
(TMRB8), and an UC3 counter value to be taken into the capture register (TB3CP1)
upon falling of TB8OUT of the 16-bit timer (TMRB8).
A frequency is then obtained from the difference between TB3CP0 and TB3CP1
based on the measurement, by generating the INTTB8 16-bit timer interrupt.
For example, if the set width of TB0FF level “1” of the 16-bit timer is 0.5 s and if the
difference between TB3CP0 and TB3CP1 is 100, the frequency is 100 / 0.5 s = 200
Hz.
