'16C74 SPI port to 93C56 - is it necessary to disab'

I've just been reading AN613 which describes how to interface 93CXX eeproms
to the 16C74.

One of the first things the code does, is to disable the interrupts.

The application I'm working on needs interrupts for keyboard entry as well
as the SCI port, however...

I can't see why the interrupts have to be disabled at all - if the SPI port
is independant of the core...

Surely, I just have to make sure that none of my interrupt routines touch
the line I'm using for the CS (port A
bit5)..

Any definitive answers??

Jim
