Parallel Port
NOTE:
For more information about initializing the parallel port, refer to the Texas
Instruments TL16C552 specification.
The TIP board contains a Texas Instruments TL165552 chip that controls the
parallel port and two serial ports (for more information about the serial ports, refer
to “Serial Ports” on page 2-5). The parallel port can be used for very fast downloads
or for connecting to a printer for logging purposes. The interrupt line from this port
is connected to a dedicated pin on the interface connector, or connected to a shared
interrupt circuit with one signal feeding back to the interrupt connector. Figure 2-
4 illustrates the parallel port connector pinout. For information about the I/O
address locations, refer to Table 2-3 and Table 2-4.
