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 an 8-bitan 8-bit indicator representing all 8
channels with each bit representing each channel
from 0 to 7. This permits the interrupt routine to quick-
The Interrupt Status Register
ly vector and serve that UART channel and determine
the source(s) in each individual routines. INT0 bit-0
represents 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.
