APPLICATION
2.2 Timer
(5) Timer application example 4 : Measurement of pulse width of FG pulse generated by motor
Outline :
The “H” level width of a pulse input to the P5
4
/CNTR
0
pin is counted by Timer X. An
underflow is detected by Timer X interrupt and an end of the input pulse “H” level is detected
by CNTR
0
interrupt.
Specifications :
The “H” level width of a FG pulse input to the P5
4
/CNTR
0
pin is counted by Timer
X.
(Example : When the clock frequency is 4.19 MHz, the count source would be
3.8
μ
s that is obtained by dividing the clock frequency by 16.
Measurement can be made up to 250 ms in the range of FFFF

.)
Figure 2.2.20 shows a connection of the timer and a setting of the division ratio, and Figure 2.2.21
shows a setting of related registers.
