3.2.8L0, L1, H0 SARAMs

The F2809 and F2808 each contain an additional 16K x 16 of single-access RAM, divided into 3 blocks (L0-4K, L1-4K, H0-8K). The F2806 contains an additional 8K x 16 of single-access RAM, divided into 2 blocks (L0-4K, L1-4K). The F2802, F2801, C2802, and C2801 each contain an additional 4K x 16 of single-access RAM (L0-4K). Each block can be independently accessed to minimize CPU pipeline stalls. Each block is mapped to both program and data space.

3.2.9Boot ROM

The Boot ROM is factory-programmed with boot-loading software. Boot-mode signals are provided to tell the bootloader software what boot mode to use on power up. The user can select to boot normally or to download new software from an external connection or to select boot software that is programmed in the internal Flash/ROM. The Boot ROM also contains standard tables, such as SIN/COS waveforms, for use in math related algorithms.
