Section 18 I/O Ports
This LSI has five ports: A, B, D, E, and F. Port A is a 16-bit port, port B is a 6-bit port, port D is a
9-bit port, and port E is a 22-bit port, all supporting both input and output. Port F is a 16-bit input-
only port.
All the port pins are multiplexed as general input/output pins and special function pins. The
functions of the multiplex pins are selected by means of the pin function controller (PFC). Each
port is provided with a data register for storing the pin data.
18.1 Port A
Port A is an input/output port with the 16 pins shown in figure 18.1.
