4.2.7 Port 6
using port mode register 6 (PM6).
Port 6 is a 4-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 and clock I/O.
Reset signal generation sets port 6 to input mode.
Figures 4-20 and 4-21 show block diagrams of port 6.
