• Manufacturer: RENESAS [Renesas Technology Corp]

Modes 2 and 6 [H8S/2351 Only]
In modes 2 and 6, port B pins function as address outputs or input ports. Input or output can be
specified on an individual bit basis. Setting a PBDDR bit to 1 makes the corresponding port B pin
an address output, while clearing the bit to 0 makes the pin an input port.
Port B pin functions in modes 2 and 6 are shown in figure 9.13.
Modes 3 and 7 [H8S/2351 Only]
In modes 3 and 7, port B pins function as I/O ports. Input or output can be specified for each pin
on an individual bit basis. Setting a PBDDR bit to 1 makes the corresponding port B pin an output
port, while clearing the bit to 0 makes the pin an input port.
Port B pin functions in modes 3 and 7 are shown in figure 9.14.
