The internal zero-wait-state ROM of the CC3220x device is at address 0x0000 0000 of the device memory and is programmed with the following components:
The bootloader is used as an initial program loader (when the serial Flash memory is empty). The CC3220x DriverLib software library controls on-chip peripherals with a bootloader capability. The library performs peripheral initialization and control functions, with a choice of polled or interrupt-driven peripheral support. The DriverLib APIs in ROM can be called by applications to reduce Flash memory requirements and free the Flash memory for other purposes.
