5.2.7 Port 6
Port 6 is an 8-bit I/O port with output latch. The P60 to P67 pins can specify the input mode/output mode in 1-
bit units with the port 6 mode register.
When pins P60 to P67 are used as input ports, a pull-up resistor can be connected in 8-bit units with bit 6 (PUO6)
of the pull-up resistor option register.
Port 6 supports the address bus function and the control signal output function in external memory expansion mode
as alternate functions.
RESET input sets port 6 to the input mode.
Figures 5-12 to 5-14 show block diagrams of port 6.
