There is a 4-KB ultra-low leakage SRAM available for use with the Sensor Controller Engine which is typically
used for storing Sensor Controller programs, data and configuration parameters. This RAM is also accessible by
the system CPU. The Sensor Controller RAM is not cleared to zeroes between system resets.
The ROM includes a TI-RTOS kernel and low-level drivers, as well as significant parts of selected radio stacks,
which frees up flash memory for the application. The ROM also contains a serial (SPI and UART) bootloader that
can be used for initial programming of the device.
