Descriptions The GM16C550 is an asynchronous communications element (ACE) that is functionally equivalent to the GM16C450, and addition-ally incorporates a 16byte FIFOs are available on both the transmitter and receiver, and can be activated by placing the device in the FIFO mode. After a reset, the registers of the GM16C550 are identical to those of the GM16C450. Features ● Fully compatible with GM16C450. ● Modem controm signals include CTS , RTS , DSR , DTR , RI and -DCD . ● Programmable serial characteristics: —5-, 6-, 7- or 8-bit characters — Even-, odd-, or no-parity bit generation and detection —1-, 11/2- or 2-stop bit generation — Baud rate generation (DC to 256K baud) ● 16 byte FIFO reduces CPU interrupts. ● Independent control of transmit, receive, line status, data set interrupts, FIFOs. ● Full status reporting capabilities ● Three-state, TTL drive capabilities for biderectional data bus and control bus. ● 40DIP/44PLCC
