Z80 DART

[Asbjoern Djupdal]

Does anybody here know anything about the Z80 DART (serial IO) chip?

I need some info about how it generates interrupts, but can't find information
about it on the web.

Hi,

The Z80 DART (dual asynchronous receiver transmitter) is the same as the
Z80 SIO chip without the synchronous options (SDLC, HDLC, etc). If you
program it the same as the SIO but make sure asychronous mode (ie using
start bit, data bits, parity if needed and stop bit/s and not the SYNC
flag) is used, the device will work fine.

Thank you. But I am unable to find information about the SIO too. Are there
programming info about the chip on the web?

The DART has the same bonding options as the SIO/0, so be careful
which sort of device you use as your model. The -1 and -2 have
different bonding options, though all three (4) versions can be
programmed the same, with varying results. If you use a DART, it
won't have the synchronous clock circuit working, but most everything
else is intact. Look at the data sheets available at www.zilog.com
for details about the bonding options. (I hope they're still there!)

Hi;
Yes, I have the data manual for that device, Zilog product spec handbook
dated 1995. if any interest in it let me know and I'll try to get the info to you.

(hard copy only).

There is nothing on the wed, BUT the Z85C30 SCC has the same internal
registers. This available from the Zilog web site.

I agree, but the chip is the same.
