4.2.7 Port 6
using port mode register 6 (PM6). When the P64 to P67 pins are used as an input port, use of an on-chip pull-up
resistor can be specified in 1-bit units by pull-up resistor option register 6 (PU6).
output (8-bit bus mode, 16-bit bus mode (lower)), write strobe signal output (16-bit bus mode (higher)), and address
strobe signal output.
Port 6 is an 8-bit I/O port with an output latch. Port 6 can be set to the input mode or output mode in 1-bit units
The output of the P60 to P63 pins is N-ch open-drain output (6 V tolerance).
This port can also be used for serial interface data I/O, clock I/O, read strobe signal output, write strobe signal
Reset signal generation sets port 6 to input mode.
Figures 4-27 to 4-29 show block diagrams of port 6.
