Pin Descriptions; Register Overview - Analog Devices SHARC ADSP-214 Series Hardware Reference Manual

• Include programmable clock and acknowledge controls for link
port transfers. Each link port has its own dedicated DMA channel.
• Provide high-speed, point-to-point data transfers to other proces-
sors, allowing differing types of interconnections between multiple
DSPs.

Pin Descriptions

The pins associated with each link port are described in the ADSP-2146x
data sheet.

Register Overview

Each link port has its own control and status register. These are described
in the following sections and in
information on the link port DMA registers, see
ter Registers" on page
registers, see "Data Buffers" on page
Control Registers (LCTLx). The control registers are used to enable the
port, to set up DMA parameters, and to configure interrupts.
