Data I/Os: Data bus.
Serial Clock for Presence-Detect: SCL is used to synchronize the
presence-detect data transfer to and from the module.
Presence-Detect Address Inputs: These pins are used to
configure the presence-detect device.
Serial Presence-Detect Data: SDA is a bidirectional pin used to
transfer addresses and data into and out of the presence-detect
portion of the module.
No Connect: These pins should be left unconnected.
