Description
Data outputs that will not be suspended
by the DCS0 and DCS1 control.
Data outputs that will not be suspended
by the DCS0 and DCS1 control.
Output error bit; generated on clock
cycle after the corresponding data
output.
Parity input. Arrives one clock cycle after
the corresponding data input.
Chip select gate enable. When HIGH,
the D1 to D28
only when at least one chip select input
is LOW during the rising edge of the
clock. When LOW, the D1 to D28
inputs will be latched and re-driven on
every rising edge of the clock.
Positive master clock input.
Negative master clock input.
Asynchronous reset input. Resets
registers and disables VREF data and
clock differential-input receivers.
Input reference voltage.
Power supply voltage.
