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.

Table B-2, Internal I/O Memory Map (X Data Memory), on page B-2 lists the memory

addresses of all internal peripherals.

Table B-3, Interrupt Sources, on page B-6 lists the interrupt starting addresses and

sources.

Table B-4, Interrupt Source Priorities Within an IPL, on page B-8 lists the priorities of

specific interrupts within interrupt priority levels.

The programming sheets appear in this manual as figures (listed in Table B-1); they show

the major programmable registers on the DSP56303.
