Experts:
I want to use MCU timer0 to capture PWM from PAD_E22. So I program codes and run on MCU1_0,
accordign to <SPRUIL1B-J721E DRA829TDA4VM-TRM>5.1.2.4, 12.10.3.4.6 and 12.10.3.5.2.3.
Input 500Hz, VPP=3V square wave to PAD_E22. PAD_E22 remains low after the program is running.
If PAD_E22 is configured as GPIO input, the injected square wave is detected at PAD_E22.
what are the reasons?
