INTRODUCTION
Figure 17 shows the high level power-up sequence for BCM2035. On power-up, the BCM2035 initializes the
hardware and begins executing the BOOT code.
The boot code performs RF programming to complete hardware initialization and sets the execution context
to the firmware. In the absence of valid RF configuration data (either via hard-wired setting, EEPROM or Flash
configuration) the boot code downloads a mini-driver to complete RF initialization.
