Figure 22.21
22.2.1
With the prescaler function, a time measurement is performed every (G1TPRj register value + 1) times a trigger
is input. The prescaler function is available in channel 6 and channel 7 in group 1.
Figure 22.21 shows register settings. Figure 22.22 shows an example of prescaler function operation.
j = 6, 7
NOTE:
1. After the PR bit in the G1TMCRj register is changed from 0 (prescaler function not used) to 1 (prescaler function used),

Measurement Function
G1TMCRj register:
G1TPRj register = n
G1FS register: FSCj bit = 1
G1FE register: IFEj bit = 1
the first time measurement may be performed when a trigger input is counted n times.

If the setting value is n (n = 00h to FFh), the base timer value is stored to
the G1TMj register every time a trigger input is counted n+1 times
