6.15 Host-Port Interface (HPI) Peripheral
6.15.1 HPI Device-Specific Information
6.15.2 HPI Peripheral Register Description(s)
TMS320DM647/TMS320DM648
Digital Media Processor
SPRS372–MAY 2007
The DM647/DM648 devices include a user-configurable 16-bit or 32-bit host-port interface (HPI16/HPI32).
The AEA14 pin controls the HPI_WIDTH, allowing the user to configure the HPI as a 16-bit or 32-bit
peripheral.
Software handshaking via the HRDY bit of the Host Port Control Register (HPIC) is not supported on the
DM647/DM648.
An HPI boot is terminated using a DSP interrupt. The DSP interrupt is registered in bit 0 (channel 0) of the
EDMA Event Register (ER). This event must be cleared by software before triggering transfers on DMA
channel 0.

The CPU can write 1 to the HINT bit to generate an interrupt to the host and it can write 1 to the DSPINT bit to clear/acknowledge an
interrupt from the host.
There are two 32-bit HPIA registers: HPIAR for read operations and HPIAW for write operations. The HPI can be configured such that
HPIAR and HPIAW act as a single 32-bit HPIA (single-HPIA mode) or as two separate 32-bit HPIAs (dual-HPIA mode) from the
perspective of the host. The CPU can access HPIAW and HPIAR independently. For details about the HPIA registers and their modes,
see the
TMS320DM647/DM648 DSP Host Port Interface (HPI) User's Guide
(literature number
SPRUEL5
