Section 17 I/O Ports
Section 17 I/O Ports
This LSI has five ports: A, B, E, F, and G. Port A is a 16-bit port, port B is a 4-bit port, and port E
is a 22-bit port, all supporting both input and output. Port F is an 8-bit port and port G is a 4-bit
port, both for input-only.
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.
17.1 Port A
Port A is an input/output port with the 16 pins shown in figure 17.1.
