3.3 73M1x22 Control Module
The 73M1x22 Control Module is responsible for the monitoring of the 73M1x22 device status and
providing the proper register settings to the 73M1x22. It will set the register settings as needed to
achieve the proper device state as dictated by the User Application. It will also monitor and report the
device status to the user application as required.

3.4 73M1x22 Hardware Module
The 73M1x22 Hardware Interface Module is responsible for providing the proper control and translation of
the MAFE interface and other hardware signals to/from the 73M1x22 device into a usable form for the
73M1x22 Data Module and the 73M1x22 Control Module.
The module is responsible for:
• Controlling the MAFE interface timing and formats.
• Formatting the incoming MAFE transactions and forwarding them to the appropriate module.
• Formatting and multiplexing the outgoing MAFE data and control transactions.
• Controlling 73M1x22 device reset signals.
• Relaying incoming interrupts.
