Description
Reserved
These bits are always read as 0. The write value
should always be 0.
SDRAM Common Deep-Power-Down Enable
This bit controls transition to and recovery from deep-
power-down mode for all channels simultaneously.
Setting DDPD to 1 causes all SDRAM channels to
transition to deep-power-down mode. Clearing DDPD
to 0 causes all SDRAM channels to recover from deep-
power-down mode. If an auto-refresh is in progress,
the transition to deep-power-down mode is delayed
until the auto-refresh completes.
0: Deep-power-down disabled
1: Deep-power-down enabled
