Description
Chip Select Gate Enable. When HIGH, the D0 to D21
inputs will be latched only when at least one Chip Select
input is LOW during the rising edge of the clock. When
LOW, the D0 to D21 inputs will be latched and redriven
on every rising edge of the clock.
Selects output drive strength: ‘HIGH’ for normal drive,
‘LOW’ for high drive. This pin will default HIGH if left
open-circuit (built-in weak pull-up resistor).
Differential master clock input pair to the register. The
register operation is triggered by a rising edge on the
positive clock input (CK).
Must be connected to a logic LOW.
Must be connected to a logic HIGH.
Asynchronous reset input. When LOW, it causes a reset
of the internal latches, thereby forcing the outputs LOW.
RESET also resets the PTYERR signal.
Input reference voltage for the SSTL_18 inputs. Two pins
(internally tied together) are used for increased reliability.
Power supply voltage.

Ground.
Ball present but not connected to die.
