LPC54606J512BD208 GPIOs on Port 5

[Jean_Marc]

Hello,

I am working with a LPC54606J512BD208, I can use GPIOs on ports 0 to 4 but I can't use GPIO on port 5, I do same as other ports but I did not succeed to make it work.

I see port 5 has only 11 I/O as other ports has 32, is there are a different way to use GPIO on port 5 or should it work same as ports 0-4 ?

Regards

Hi,

There is nothing special in pio5 with other port. Please make sure if:

1. the GPIO5_RST bit in PRESETCTRL2 is release,

2. the GPIO5 bit in AHBCLKCTRL2 is set,

3. function select to GPIO,

4. GPIO_MASK and GPIO_DIR is set correctly.
