Programming Reference
This reference for programmers includes a table showing the addresses of all DSP
memory-mapped peripherals, an exception priority table, and programming sheets for the major
programmable DSP registers. The programming sheets are grouped in the following order:
central processor, Phase Lock Loop (PLL), Host Interface (HI08), Enhanced Synchronous Serial
Interface (ESSI), Serial Communication Interface (SCI), Timer, and GPIO. Each sheet provides
room to write in the value of each bit and the hexadecimal value for each register. You can
photocopy these sheets and reuse them for each application development project. For details on
the instruction set of the DSP56300 family of DSPs, see the DSP56300 Family Manual.
