11.3 SRAM Memory Configuration

Retention

Depending on the application and power budget needs, system memory can be retained in Standby or Hibernate sleep modes. The amount of the SRAM retained in this mode is software selectable, by writing the RAMCFG bits in the Power Manager Standby Configuration register and Hibernate Configuration register respectively (PM.STDBYCFG.RAMCFG and PM.HIBCFG.RAMCFG).
