This is an application example where the pulse width of the signal input to the TI00n pin is measured.
By setting CRC0n, the count value can be captured to CR00n in the phase reverse to the falling edge of the TI00n pin
(i.e., rising edge) and to CR01n at the falling edge of the TI00n pin.
The high- and low-level widths of the input pulse can be calculated by the following expressions.
• High-level width = [CR01n value] – [CR00n value] × [Count clock cycle]
• Low-level width = [CR00n value] × [Count clock cycle]
If the reverse phase of the TI00n pin is selected as a trigger to capture the count value to CR00n, the INTTM00n
signal is not generated. Read the values of CR00n and CR01n to measure the pulse width immediately after the
INTTM01n signal is generated.
However, if the valid edge specified by bits 6 and 5 (ES1n1 and ES1n0) of prescaler mode register 0n (PRM0n) is
input to the TI01n pin, the count value is not captured but the INTTM00n signal is generated. To measure the pulse
width of the TI00n pin, mask the INTTM00n signal when it is not used.
