CHAPTER 6 PORT FUNCTIONS
6.1 Port Functions
The µ PD78054 and 78054Y subseries units incorporate two input ports and sixty-seven input/output ports. Figure
6-1 shows the port configuration. Every port is capable of 1-bit and 8-bit manipulations and can carry out considerably
varied control operations. Besides port functions, the ports can also serve as on-chip hardware input/output pins.
