(1) Functions of each port
The V850E/IA2 has the ports shown below.
Any port can operate in 8-bit or 1-bit units and can provide a variety of controls.
Moreover, besides its function as a port, each has functions as the I/O pins of on-chip peripheral I/O in control
mode.
Refer to (3) Port block diagrams for a block diagram of the block type of each port.
