SDRAM Common Power-Down Enable

This bit controls transition to and recovery from power-

down mode for all channels simultaneously. Setting

DPWD to 1 causes all channels to transition to power-

down mode. Clearing DPWD to 0 causes all channels

to recover from power-down mode. If an auto-refresh is

in progress, the transition to power-down mode is

delayed until the auto-refresh completes.

0: Power-down disabled

1: Power-down enabled
