GENERAL DESCRIPTION
The XR17C1581 (158) is an octal Universal
Asynchronous Receiver and Transmitter (UART). The
device is designed to meet the 32-bit PCI Bus and
high bandwidth requirement in communication
systems. The global interrupt source register
provides a complete interrupt status indication for all
8 channels to speed up interrupt parsing. Each UART
has its own 16C550 compatible set of configuration
registers, transmit and receive FIFOs of 64 bytes,
fully programmable transmit and receive FIFO level
triggers, transmit and receive FIFO level counters,
automatic RTS/CTS or DTR/DSR hardware flow
control with programmable hysteresis, automatic
software (Xon/Xoff) flow control, IrDA (Infrared Data
Association) encoder/decoder, 8 multi-purpose
definable inputs/outputs, and a 16-bit general
purpose timer/counter.

DESCRIPTION
UART channel 6 Transmit Data or infrared transmit data.
UART channel 6 Receive Data or infrared receive data. Normal RXD input
idles HIGH. The infrared pulses typically idle LOW but can be inverted inter-
nally prior the decoder by FCTR[4].
UART channel 6 Request to Send or general purpose output (active low).
UART channel 6 Clear to Send or general purpose input (active low).
UART channel 6 Data Terminal Ready or general purpose output (active low).
UART channel 6 Data Set Ready or general purpose input (active low).
UART channel 6 Carrier Detect or general purpose input (active low).
UART channel 6 Ring Indicator or general purpose input (active low).
UART channel 7 Transmit Data or infrared transmit data.
UART channel 7 Receive Data or infrared receive data. Normal RXD input
idles HIGH. The infrared pulses typically idle LOW but can be inverted inter-
nally prior the decoder by FCTR[4].
UART channel 7 Request to Send or general purpose output (active low).
UART channel 7 Clear to Send or general purpose input (active low).

figuration Register MPIOSEL, MPIOLVL, MPIOINV, MPIO3T and MPIOINT.
O Serial clock to EEPROM. An internal clock of CLK divide by 256 is used for
reading the vendor and sub-vendor ID during power up or reset. However, it
can be manually clocked thru the Configuration Register REGB.
