How to write a value to a port in DIO module AUTOSAR?

I am working in an AUTOSAR project on a STM32 NUCLEO-F767ZI board and I have to write the value for a port in the DIO module. I know that there is a function called HAL_GPIO_WritePin(), but how can I make to write the value for an entire port?

You can do that by writing the value for each channel in that port.

The ports usually have 16 channels so the value you want to write is a 16 bit number containing 0 and 1 (LOW and HIGH). So for each bit in that number you call the function HAL_GPIO_WritePin() and use the parameter RESET for 0 and SET for 1 to write the value to the corresponding channel.
