22.2.2
With the gate function, trigger inputs are ignored for a specific period of time. After a time measurement is
performed by the first trigger input, the subsequent trigger inputs are all ignored. Thereafter, one trigger input is
accepted every time either of the following conditions is met:
The gate function is available in channel 6 and channel 7.
Figure 22.23 shows register settings. Figure 22.24 shows an example of gate function operation.
When j=6, q=4 and when j=7, q=5
When the GOC bit in the G1TMCRj register is set to 1
•
•
(Gate function is disabled by matching the base timer and the G1POq register)
Base timer value matches the G1POk register value (k = 4, 5) (Waveform generation function is used).
The G1PO4 register is used to control the gate function in channel 6.
The G1PO5 register is used to control the gate function in channel 7.
Set the GSC bit in the G1TMCRj register to 1. (j = 6, 7)
