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 PBDDR bits to 1 makes the corresponding port B pins
address outputs, while clearing the bits to 0 makes the pins input ports.
Port B pin functions in mode 6 are shown in figure 8.11
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 PBDDR bits to 1 makes the corresponding port B pins
output ports, while clearing the bits to 0 makes the pins input ports.
Port B pin functions in mode 7 are shown in figure 8.12.
Note: * Modes 6 and 7 are not available in the ROMless versions.
