4.9 General Purpose Input/Output (GPIO)
The CS7410 provides a number of General Purpose Input/Output (GPIO) pins, each with individual output
three-state controls, and a number of General Purpose Output (GPO) pins. Table 16 shows the 17 dedicat-
ed GPIO pins. A naming scheme for these pins was chosen to encourage system designers to adhere to
standardized pin usage. Table 17 shows the GPIO and GPO pins that can be redefined from other functions.
For redefined pins, mode control register bits select the normal function or GPIO/GPO function for the pins.
Table 17 also indicates which mode bit controls each pin.
