PWM输出停止后，能否通过设置IO口输出模式进行GPIO高低电平输出。我通过demo板验证，发现pwm_stop后无法操作IO。

Hello.

When TCPWM is assigned to GPIO, a MUX is used to select this TCPWM function.  To select GPIO function, the MUX needs to be changed to point to GPIO.

See this thread where GPIO and SPI were used.  This will be similar solution to TCPWM and GPIO for your project.

You will need to find the Technical Reference Manual for your PSoC.  The link above is for 4200 family with UDB blocks.  If your device has Smart/IO, then there may be something similar for solution.
