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.
SSTL_2 reference voltage.
Power Supply: +2.6V ±0.1V.
