Hi @NermeenShaban,
Currently, the driver supports only channels 0 through 7 for FlexIO, even though the reference manual states the 32 FlexIO channels:

The drivers may not encompass the whole limitations of the MCU, for which further implementation must be based on the client's side.
Best regards,
