Memory
The flash memory provides nonvolatile storage for code and data. The flash memory is in-system
programmable.
The SRAM (static RAM) can be used for both storage of data and execution of code and is split into two
4-KB blocks and two 6-KB blocks. Retention of the RAM contents in standby mode can be enabled or
disabled individually for each block to minimize power consumption. In addition, if flash cache is disabled,
the 8-KB cache can be used as a general-purpose RAM.
The ROM provides preprogrammed embedded TI RTOS kernel, Driverlib and lower layer protocol stack
software (802.15.4 MAC and
Bluetooth
Low Energy Controller). It also contains a bootloader that can be
used to reprogram the device using SPI or UART.

Debug
The on-chip debug support is done through a dedicated cJTAG (IEEE 1149.7) or JTAG (IEEE 1149.1)
interface.
