A search of the web yielded lots of links, but no
datasheet. I want to
know
how to program it and its electrical characteristics.
You know, the stuff
on a datasheet. Zilog's web site doesn't have it.
8530 is the Zilog SCC chip, as is the 8030. The differ only in bus
interface.
The 8530 is the non multiplexed bus part.
It's a dual channel serial device with DMA and interrupt logic for Z80
series cpus. Programming of the functions are similar to Z80 SIO
and related parts in a general way. It's a nontrivial device to use.
Contact Zilog for data or check their page under SCC.
[ Its the chip used in the Apple Lisa and Mac and LOTS
of other devices. ]
You sure of this?? It's not really friendly to the 68k buses.
