ADVANCE INFORMATION
Refer to the PDF data sheet for device specific package drawings
The purpose of this section is to explain the boot read-only memory (ROM) code functionality for the C29x CPU core's, including the boot procedure. This section also discusses the functions and features of the boot ROM code, and provides details about the ROM memory-map contents. On every reset, the device executes a boot sequence in the ROM depending on the reset type and boot configuration. This sequence initializes the device to run the application code. For the CPU, the boot ROM also contains peripheral bootloaders that can be used to load an application into RAM. These bootloaders can be disabled for safety or security purposes.
See Table 7-29 for details on available boot features for the C29x CPU. Additionally, Table 7-30 shows the sizes of the various ROMs on the device.
