Fixed-Point Digital Signal Processor

SPRS095O – MARCH 1999 – REVISED JANUARY 2005

In nonmultiplexed mode, a host with separate address/data buses can access the HPI16 data register

(HPID) via the HD 16-bit bidirectional data bus, and the address register (HPIA) via the 18-bit HA address

bus. The host initiates the access with the strobe signals (HDS1, HDS2, HCS) and controls the direction of

the access with the HR/W signal. The HPI16 can stall host accesses via the HRDY signal. Note that the

HPIC register is not available in nonmultiplexed mode since there are no HCNTL signals available. All

host accesses initiate a DMA read or write access. Figure 3-8 shows a block diagram of the HPI16 in

nonmultiplexed mode. Figure 3-9 shows the HPI memory map.
