INPUT FUNCTION
M12S64322A
Makes data output Hi-Z, t
SHZ
after the clock and masks the output.
Blocks data input when DQM active.
Data inputs / outputs are multiplexed on the same pins.
Power and ground for the input buffers and the core logic.
Isolated power supply and ground for the output buffers to provide
improved noise immunity.
This pin is recommended to be left No Connection on the device.
