PCI BUS OCTAL UART

1.2.1
The XR17C158 has a 32-bit wide register [INT0,
INT1, INT2 and INT3] to provide interrupt information
and supports two interrupt schemes. The first scheme
is a 8-bit indicator representing all 8 channels with
each bit representing each channel from 0 to 7. This
permits the interrupt routine to quickly vector and
The Interrupt Status Register
serve that UART channel and determine the
source(s) in each individual routines. INT0 bit-0
represnts the interrupt status for UART channel 0
when its transmitter, receiver, line status, or modem
port status requires service. Other bits in the INT0
register provide indication for the other channels with
bit-7 representing UART channel 7 respectively.
