• Manufacturer: RENESAS [Renesas Technology Corp]

Mode 6: In mode 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 mode 6 are shown in figure 9.13
Mode 7: In mode 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 mode 7 are shown in figure 9.14.
