Offset:
0x1340
Retention:
Retained
IsDeepSleep:
No
Comment:
These registers control the system SRAM 0 power states of a single macro. System SRAM 0
consists of up to sixteen 32 kB macros. Each macro is a single power partition and is
controlled through a dedicated control field in one of these registers.

RETAINED
2
Keep SRAM in Retained mode. This will turn OFF the
SRAM periphery power, but array power is ON to
retain memory contents.
The SRAM contents will be retained in DeepSleep
system power mode.
