9 / 22 page IA82050 Data Sheet Asynchronous Serial Controller February 25, 2011 IA211030617-08 http://www.Innovasic.com UNCONTROLLED WHEN PRINTED OR COPIED Customer Support: Page 9 of 22 1-888-824-4184 ® 3. Functional Overview 3.1 Transmitter The Transmit function consists of a one-character FIFO, and a Transmit Engine. 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 For more details, see Chapter 5, Register Descriptions. 3.2 Receiver The Receiver function consists of a one-character 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 For more details, see Chapter 5, Register Descriptions. 3.3 Bus Interface The Bus Interface is a simple interface that allows a micro-processor or micro-controller to read and write the IA82050 Registers. It consists of the following I/O lines: • A0, A1, A2 : 3-Bit Address • D0-D7 : 8-Bit Data • RDn: Active Low Read Enable • WRn: Active Low Write Enable • CSn: Active Low Chip Select • INT: Interrupt Output • RESET: Chip Reset |
