Cpld Module (cpld)

Description

Cpld module provides the basic functionality to access the register set of the device. Simple operations are provided to set/get a 8bit register value or 1bit fields.

This module is normally used as part of the logic module. Specific functionality of the device is defined and handled in the logic module.

Target Hardware Resource

The OSC plattform is optionally featured with a CPLD device attached to the DSP External Bus Interface Unit (EBIU) on the ASYNC Memory Bank 0. 8 Bit parallel interconnection is used. The device is controllable by a set registers located at this memory space.

Dependencies

No submodules required. A device driver is used to map the device register memory to user space.
