C5505 GPIO question

Todd Anderson78572

All:

The datasheet says that there are 26 pins available as GPIO. However, looking at the pins, there are actually 32 pins designated as GPIO lines. 6 of these pins are shared with the EMIF. Assuming that one is using the EMIF, it would then allow for up to 26 pins to be used as GPIO. If the EMIF is not used, the number actually goes up to 32 pins, right?

Regards,

Todd Anderson

    Please refer to the parallel and serial ports pin multiplexing tables, the most you can bring out are 26 GPIOs at the maximum.
