Block Diagram
Above block diagram shows 5 main components on the PDIUSBD12 evaluation board. Beside bus
transceiver, address/command decoder and PDIUSBD12, a general input port and a general output
port are included in the design. These input and output ports are designed for test purposes, such as
test switches and test LEDs. They also act as glue logic to adapt the PDIUSBD12 to the ISA bus. For
example, ISA interrupt is edge triggered, but PDIUSBD12 interrupt is level triggered. The MSB of the
general output port is used as interrupt enable to convert level triggered interrupt to edge triggered.
I/O Mapping
PDIUSBD12 evaluation board uses 8 I/O addresses:
