(4) Pulse Width Measurement Mode
• Mode selection
This mode can be selected by setting “11” to the timer X
operating mode bits (bits 1 and 0) and the timer Y operating
mode bits (bits 5 and 4) of the timer XY mode register (address

• Explanation of operation

the term of one rising edge input until the next falling edge input
(“H” term).
• Precautions

The count operation can be stopped by setting “1” to the timer X
count stop bit (bit 3) and the timer Y count stop bit (bit 7) of the
timer XY mode register (address 0023
bit is set to “1” each time the timer underflows.
• Precautions when switching count source
When switching the count source by the timer 12, X and Y count
source selection bits, the value of timer count is altered in
inconsiderable amount owing to generating of thin pulses on the
count input signals.
Therefore, select the timer count source before setting the value
to the prescaler and the timer.
