SDRAMC supports an SDRAM deep-power-down mode. In deep-power-down mode SDRAMC
issues a deep-power-down command and drives the SDCKE signal low level.
Transition to and recovery from deep-power-down mode are performed using the SDRAM deep-
power-down control register (SDDPDCNT).
Setting the DDPD bit to 1 causes SDRAMC to put all channels into deep-power-down mode.
Clearing the DDPD bit to 0 causes SDRAMC to recover from deep-power-down mode.
During recovery from deep-power-down mode, SDRAMC issues a deep-power-down exit
command and drives the SDCKE signal high level.
Following recovery from deep-power-down exit, wait for the duration designated for the SDRAM
being used and then execute an initialization sequence.
