Nibble utilization for pin efficient 1x32 interface using one x32 component in the non-flipped configuration is shown in the following figure. For maximum interface performance use the 1x32 pinout described in the Figure titled "Nibble utilization for 1x32 component interface (Non-Flipped)". DQ indicates data nibbles, AC indicates Address/Command/Control nibbles, sys_clk indicates a nibble comprising the System Clock pair, RESET_n, and ALERT_n signals. Refer to Clocking for System Clock details.
