TC1765
Preliminary
Parallel Ports
The TC1765 has 77 digital input/output port lines organized into four parallel 16-bit ports
(Port 0 to Port 3), one 8-bit port (Port 4), and one 5-bit port (Port 5). Additionally,
24 analog input port lines are available. The External Bus Unit (EBU) is provided with
dedicated data, address, and control lines. A 16-bit Trace Port is available only in the
TC1765T.
The digital parallel ports Port 0 to Port 5 can be all used as general purpose I/O lines or
they can perform input/output functions for the on-chip peripheral units. The on-chip
External Bus Interface Unit allows to communicate with external memories, external
peripherals, or external debugging devices. An overview on the port-to-peripheral unit
assignment is shown in Figure 4.
