I use the MCU is R7S910035, when I config GPT ，set it 100us every period,and start it ,I use a GPIO as a signal in the timer, and every time I enter the GPT, the signal flips. I use an oscilloscope to capture the waveform and sometimes there is no signal. There is only one GPT in my program and no other interrupts are enabled.----UPDATE-----
My requirement is for a stable timer with a cycle of 100us. But the GPT and CMT I configured with AP4 cannot be stable, and the oscilloscope will capture a situation where there is no signal for several milliseconds. I only configured one timer without any other interrupts. May I ask why this is happening?
