protocols. You can also use some of them as GPIO pins for digital inputs and outputs.

C0 through C9 - These are the ACBUS pins on the FT232H chip and are mainly used as GPIO pins for digital inputs and

outputs. Note that pins C8 and C9 are not controlled by software and can only be assigned functionality by changing the

EEPROM of the chip. You'll learn more about these two pins in the more info section.
