14.2.6 Port 6
(1) Function of P6 pins
Port 6
Port 6 is a 6-bit I/O port for which I/O settings can be controlled in 1-bit units.
Remark
Port 6 includes the following alternate functions.
Note Software pull-up function
After reset:
P6
Port 6 is a 6-bit I/O port for which I/O settings can be controlled in 1-bit units. I/O settings are controlled via the
port 6 mode register (PM6).
In output mode, the values set to each bit are output to port 6 (P6).
When using this port in input mode, the pin statuses can be read by reading P6. Also, the P6 (output latch) values
can be read by reading P6 while in output mode.
A software pull-up function is not implemented.
When using the alternate-function A16 to A21 pins, set the pin functions via the memory expansion mode register
(MM). This does not affect PM6.
When a reset is input, the settings are initialized to input mode.

When port 6 (P6) is read, the pin levels at that time are read. Writing to P6
writes the values to that register. This does not affect the input pins.
When port 6 (P6) is read, the P6 values are read. Writing to P6
writes the values to that register, and those values are immediately output.
