Selectable function
When the external trigger is input, the base timer value is stored into the G1TMi register (i = 0 to 7). The time
measurement function is available in group 1. Table 22.4 shows specifications of the time measurement function.
Table 22.5 lists pin settings for the time measurement function. Figure 22.19 shows register settings. Figure 22.20
shows an example of time measurement function operation.
Time Measurement Function (Input Capture)

Time Measurement Function Specifications
• Without prescaler: every time a valid edge is input
Group 1: Channels 0 to 7
Trigger input
Selectable among rising edge, falling edge, or both edges
Time measurement starts when all of the following conditions are met:
• Base timer count starts
• Set the FSCi bit in the G1FS register to 1 (time measurement function selected)
• Set the IFEi bit in the G1FE register to 1 (channel i’s function enabled)
Time measurement stops when any of the following conditions is met:
• Set the IFEi bit to 0 (channel i’s function disabled)
• Base timer count stops (function in all channels disabled)
• With prescaler (channels 6 and 7):
• Digital filter function
• Prescaler function (channels 6 and 7)
• Gate function (channels 6 and 7)
The TM1iR bit in the IIOkIR register (k = 0 to 4, 8 to 10) becomes 1 (interrupt
requested) when an interrupt request is generated.
(See Figure 11.18 IIO0IR to IIO11IR Registers)
every (G1TPRj register value + 1) times a valid edge is input (j = 6, 7)
The digital filter samples a trigger input signal level using f1 or fBT1 and passes
the pulse that have matched its signal level three times
Time measurement is performed every (G1TPRj register value + 1) times a
trigger is input
After a time measurement is performed by the first trigger input, the subsequent
trigger inputs are all ignored. Thereafter, one trigger input is accepted when
either of the following conditions is met:
- Base timer value matches the G1POn register value (n = 4, 5)
- Set the GSC bit in the G1TMCRj register to 1
