Host Interface (HI08)
6.3 Overview
The HI08 is partitioned into two register banks, as Figure 6-1 shows. The host-side register bank
is accessible only to the host, and the DSP-side register bank is accessible only to the DSP core.
For the host, the HI08 appears as eight byte-wide locations mapped in its external address space.
The DSP-side registers appear to the DSP core as six 24-bit registers mapped into internal I/O X
memory space and therefore accessible via standard DSP56300 instructions and addressing
modes.
