NOTES:
In synchronization with an external trigger input, the value of the base timer is stored into the G1TMj
register (j=0 to 7). Table 13.5 shows specifications of the time measurement function. Table 13.6 shows
register settings associated with the time measurement function. Figures 13.19 and 13.20 display opera-
tional timing of the time measurement function. Figure 13.21 shows operational timing of the prescaler
function and the gate function.

Channels 0 to 7

The IFEj bit in the G1FE register should be set to "1" (channels j function
enabled) when the FSCj bit (j=0 to 7) in the G1FS register is set to "1" (time
measurement function selected).
The IFEj bit should be set to "0" (channel j function disabled)
•No prescaler : every time a trigger signal is applied
•Prescaler (for channel 6 and channel 7):
The G1IRi bit (i=0 to 7) in the interrupt request register (See Figure 13.9) is
set to "1" at time measurement timing

The digital filter samples a trigger input signal level every f
cycles and passes pulse signal matching trigger input signal level three
times
Time measurement is executed every
trigger signal is applied
After time measurement by the first trigger input, trigger input cannot be
accepted. However, while the GOC bit in the G1TMCRk register is set to
"1" (gate cleared by matching the base timer with the G1POp register (p=4
when k=6, p=5 when k=7)), trigger input can be accepted again by
matching the base timer value with the G1POp register setting
