3. Functional Overview

3.1 Transmitter

The Transmit function consists of a 4 11 bit FIFO, and a Transmit Engine. The 4 11 FIFO is

configurable as any depth between one and four words inclusive. The transmit engine is

responsible for reading the data out of the FIFO and placing it in the proper order on the TXD pin.

The transmit engine is highly configurable to be compatible with numerous formats, including

16450 and 8250 modes of communication. Transmit Communication parameters that can be

programmed include:

Parity modes

Stop Bits

Character Length

FIFO Depth

Clocking Options

RTS and CTS modes

For more details, see Section 3.4, Register Description.

3.2 Receiver

The Receiver function consists of a 4 11 configurable FIFO and a Receive Engine. The receive

engine is responsible for sampling the data on the RXD input pin, formatting the data, and placing

the data in the FIFO. The receive engine is highly configurable with parameters that include:

Parity modes

Stop Bits

Character Length

FIFO Depth

Clocking Options

Address Matching Options

Control Character Detection

RTS and CTS modes

For more details, see Section 3.4, Register Description.

3.3 Bus Interface

The Bus Interface is a simple interface that allows a micro-processor or micro-controller to read

and write the IA82510 Registers. It consists of the following I/O lines:
