The device includes a user-configurable 16-bit Host-port interface (HPI16).
The host port interface (UHPI) provides a parallel port interface through which an external host processor can directly access the processor's resources (configuration and program/data memories). The external host device is asynchronous to the CPU clock and functions as a master to the HPI interface. The UHPI enables a host device and the processor to exchange information via internal or external memory. Dedicated address (HPIA) and data (HPID) registers within the UHPI provide the data path between the external host interface and the processor resources. A UHPI control register (HPIC) is available to the host and the CPU for various configuration and interrupt functions.
