Preliminary
External Bus Unit
The External Bus Unit (EBU) of the TC1775 is the interface between external memories
and peripheral units and the internal memories and peripheral units. The basic structure
of the EBU is shown in
Figure 12
The EBU is primarily used for the following two operations:
• Communication with external memories or peripheral units via the FPI Bus
• Instruction fetches from the PMU to external Burst Flash program memories
The EBU controls all transactions required for these two operations and in particular
handles the arbitration between these two tasks.
The types of external devices/bus modes controlled by the EBU are:
• INTEL style peripherals (separate RD and WR signals)
• ROMs, EPROMs
• Static RAMs
• Demultiplexed A/D bus
• Multiplexed A/D bus
The PMU controls accesses to external code memories. It especially supports:
Note: Instruction fetches of the PMU from external Burst Flash program memories are
