UART with 32-byte FIFOs and IrDA encoder/decoder
Description
Serial data input. RX is serial data input from a connected
communications device.
Serial data output. TX is composite serial data output to a
connected communication device. TX is set to the marking
(HIGH) level as a result of Master Reset.
Transmitter ready. Transmitter DMA signaling is available
with TXRDY. When operating in the FIFO mode, one of two
types of DMA signaling can be selected using FCR[3]. When
operating in the 16C450 mode, only DMA mode 0 is allowed.
Mode 0 supports single-transfer DMA in which a transfer is
made between CPU bus cycles. Mode 1 supports
multi-transfer DMA in which multiple transfers are made
continuously until the transmit FIFO has been filled.
Write inputs. When either IOW or IOW is active (LOW or
HIGH, respectively) and while the UART is selected, the
CPU is allowed to write control words or data into a selected
UART register. Only one of these inputs is required to
transfer data during a write operation; the other input should
be tied to its inactive level (i.e., IOW tied LOW or IOW tied
HIGH).
Crystal connection or External clock input.
Crystal connection or the inversion of XTAL1 if XTAL1 is
driven.
not connected
