TP3465 MICROWIRE
TM
Interface Device (MID)
General Description
The MICROWIRE
TM
Interface Device MID gives a general
microprocessor (such as National Series 32000
é
proces-
sors, Intel 80C188, 80C86 or 80286, Motorola 6800 and
68000 family of processors) the ability to communicate effi-
ciently with up to eight peripheral devices via the serial MI-
CROWIRE interface. The MID causes each of the peripheral
devices to appear to the
m
P as memory mapped locations,
by performing all the data serialization and transfer proto-
cols to and from the peripherals.
Applications
Y
ISDN Terminal Adapters
