description (continued)

per byte for the receiver FIFO. In the FIFO mode, there is a selectable autoflow control feature that can

significantly reduce software overload and increase system efficiency by automatically controlling serial data

flow using RTS output and CTS input signals.

The TL16PNP550A responds to the plug-and-play (PnP) autoconfiguration process. The autoconfiguration

process puts all PnP cards in a configuration mode, isolates one PnP card at a time, assigns a card select

number (CSN), and reads the card resource data structure from the EEPROM. After the resource requirements

and capabilities are determined for all cards, the autoconfiguration process uses the CSN to configure the card

by writing to the configuration registers. The TL16PNP550A only implements configuration registers for I/O

applications with one logical device and no direct memory access (DMA) support. Finally, the process activates

the TL16PNP550A card and removes it from configuration mode. After the configuration process, the ACE starts

responding to industry standard architecture (ISA) bus cycles. This device can also be configured to bypass

the PnP autoconfiguration sequence. In this mode the TL16PNP500A can be configured to select the COM port

address and IRQ level. In the UART bypass mode, the UART is disabled and this device is configured to be a

stand-alone PnP controller that supports one logical device and no DMA support.

The TL16PNP550A performs serial-to-parallel conversion on data received from a peripheral device or modem

and parallel-to-serial conversion on data received from its CPU. The CPU can read and report on the status of

the ACE operation. Reported status information includes the type of transfer operation in progress, the status

of the operation, and any error conditions encountered.

The TL16PNP550A includes a clock prescalar that divides the 22-MHz input clock by 12, 6, 3, or 1. The prescalar

output clock is fed to the programmable baud rate generator, which is capable of dividing this clock by divisors

from 1 to (216 – 1).
