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.
[ 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.
