Name
z8530_status —
Handle a PIO status exception
Synopsis
void z8530_status ( | struct z8530_channel * chan); |
Arguments
chan
Z8530 channel to process
Description
A status event occurred in PIO synchronous mode. There are several
reasons the chip will bother us here. A transmit underrun means we
failed to feed the chip fast enough and just broke a packet. A DCD
change is a line up or down.
