Subject: Programming the 5380 (Mac) serial port for microcontroller ports

Is it possible to program the serial port controller on the
Macintosh (a Zilog 5380) to talk to the high-speed
'Serial Peripheral Interface' (SPI, a synchronous master/slave protocol)
on a Motorola 6811?  Or to any other equivalent microcontroller
serial port?  (Asynch. operations with start/stop synch etc. are
too slow (125 kBaud max on the 6811))

Alternatively, does anyone know of a different microcontroller chip with
a faster serial port and A/D converters?

Thanks in advance.
