Table 15-3 shows relationships between PADAT bits and parallel port pins when PADAT is
accessed. The effect differs when the parallel port pin is an input or output.
The following results occur when a parallel port pin is configured as an input:
The following results occur when a parallel port pin is configured as an output:
These relationships are also described in Table 15-3.
15.1.4 Code Example
The following code example shows how to set up the parallel port. Here, PP[7:0] are
general-purpose I/O, PP[3:0] are inputs, and PP[7:4] are outputs.
