| description: | |
| Value to use for DDR-Backup Power (default 0). |
| This is a bitmask that specifies which DDR power rails need to be kept |
| powered when backup mode is entered, for system suspend: |
| - bit 0: DDR0 |
| - bit 1: DDR1 |
| - bit 2: DDR0C |
| - bit 3: DDR1C |
| These bits match the KEEPON_DDR* bits in the documentation for the "BKUP |
| Mode Cnt" register. |
