—
Data Input/Output: Bidirectional data bus.
Data Strobe: Output with read data, input with write data for
source synchronous operation. Edge-aligned with read data,
center aligned with write data. DQS# is only used when
differential data strobe mode is enabled via the LOAD MODE
command.
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.
