The IWE8 microprocessor interface allows connection of Intel type microprocessors as
well as Motorola type microprocessors (e.g. the PowerPC).
The Microprocessor Interface Mode is determined via the status of the pins PMT and
TBUS at the positive edge of the internal reset. Therefore, PMT and TBUS levels have
to be kept at least 3 clock cycles after deassertion of RESET.

The mode currently assigned to the microprocessor interface is visible via “mtypsel” in

The connection of the 16 bit Intel compatible asynchronous microprocessor interface to
an Intel 386EX processor is shown in
If the ready signal at pin MPRDY shall be used, a glue logic between MPRDY of the
IWE8 and RDY of the 386EX is required, which generates an active low signal with 1
microprocessor cycle length after a rising edge detection of the MPRDY signal.
