† Valid only if the I/O function is selected on the pin.
‡ If the GPIO pin is configured as an output, these bits can be written to. If the pin is configured as an input, these bits are read from.
§ If the DIR bit is 0, the GPIO pin functions as an input. For a value of 1, the pin is configured as an output.
NOTE: GPIO pins IOPD2 to IOPD7 are dedicated I/O pins in ’F243. These pins are not available in the ’F241.
