78 CHAPTER 4 PORT FUNCTIONS 4.2.5 Port 5 Port 5 is an 8-bit input/output port with output latch. Input mode/output mode can be specified for pins P50 to P57 in 1-bit units with port mode register 5 (PM5). For pins P50 to P57, an on-chip pull-up resistor can be specified in 1-bit units with pull-up resistor option register 5 (PU5). This port can also be used as an address bus in external memory expansion mode. RESET input sets port 5 to input mode. Figure 4-6 shows a block diagram of port 5.

CHAPTER 4 PORT FUNCTIONS 4.2.6 Port 6 Port 6 is a 4-bit input/output port with output latch. Input mode/output mode can be specified for pins P64 to P67 in 1-bit units with port mode register 6 (PM6). For pins P64 to P67, an on-chip pull-up resistor can be specified in 1-bit units with pull-up resistor option register 6 (PU6). This port can also be used as a control signal output in external memory expansion mode. RESET input sets port 6 to input mode. Figure 4-7 shows a block diagram of port 6. Caution When external wait is not used in external memory expansion mode, P66 can be used as an input/output port.
