Figure 5-11
Port ‘write/read’ switch settings
NOTE
A port configured for output, such as port A in this case, can be set
for either read or write mode. In write mode, you may toggle bit
settings high or low by clicking the DIP switches. In read mode,
however, DIP switches only monitor the bit settings currently in the
I/O register; you cannot change bit settings.
9. Using the DIP switches on the PIO Control Panel, set ports A, B, and C to bit pattern 1, as
shown in Figure 5-12. Bit pattern 1 corresponds to a byte value of 55 in hexadecimal.
