GPIO pin multiplexing in C6455 [Copy link]

In addition, when using GPIO, you also need to consider the pin reuse of the corresponding chip. Taking 6455 as an example, the GPIO pin reuse is as shown in the figure below:

It can be seen that most of the 16 GPIO pins can be reused. The GPIO module can be enabled by configuring the peripheral configuration register of 6455. That is, set the GPIO corresponding position in the PERCFG0 register of 6455 to 1, as shown below:
