18.3.1.6.1 Enabling Retention RAM in the Deep Sleep Mode

There is no separate backup SRAM available for the PIC32CX-BZ3 family of devices. Any context saving needs to be done in the data FlexRAM (SRAM). Depending on the size requirement of the data to be retained while in the Deep Sleep mode, the right size FlexRAM (SRAM) may be selected in the WCMSIZ register. See WCMSIZ from Related Links.
