There are no dedicated pin for these signals.

The device has no ready to use build in functionality for I2C or SMBus.

You must include these functionality as ip blocks into this device.

it depends on the ip function size wheter it fits into the device or not.

if both functions can be included it depends on if you can combine their signals how many pins you will need. for example if you can combine the clock signal for both ip functions.

and if you can combine the bidirectonal data io signal.
