Section 28 I/O Port
Section 28 I/O Port
This LSI has seventeen 8-bit ports* (ports A to T). All port pins are multiplexed with other pin
functions. The pin function controller (PFC) handles the selection of pin functions and pull-
up/pull-down MOS control. Each port has one data register for the storage of pin data.
Note: * On some ports, not all of the eight bits are effective.
28.1 Register Descriptions
Table 28.1 shows the register configuration of I/O ports. Table 28.2 shows the register states in
each operating mode.
