TMS320UC5402

FIXED-POINT DIGITAL SIGNAL PROCESSOR

SPRS096A – APRIL 1999 – REVISED DECEMBER 1999

POST OFFICE BOX 1443

• HOUSTON, TEXAS 77251–1443

parallel I/O ports

The ’UC5402 has a total of 64K I/O ports. These ports can be addressed by the PORTR instruction or the

PORTW instruction. The IS signal indicates a read/write operation through an I/O port. The ’UC5402 can

interface easily with external devices through the I/O ports while requiring minimal off-chip address-decoding

circuits.

enhanced 8-bit host-port interface (HPI-8)

The ’UC5402 host-port interface, also referred to as the HPI-8, is an enhanced version of the standard 8-bit HPI

found on earlier ’54x DSPs (’542, ’545, ’548, and ’549). The HPI-8 is an 8-bit parallel port for interprocessor

communication. The features of the HPI-8 include:

Standard features:

D Sequential transfers (with autoincrement) or random-access transfers

D Host interrupt and ’54x interrupt capability

D Multiple data strobes and control pins for interface flexibility

Enhanced features of the ’UC5402 HPI-8:

D Access to entire on-chip RAM through DMA bus

D Capability to continue transferring during emulation stop
