8.1.6 Port
6
Port 6 is an 8-bit I/O port. Port 6 pins can also function as the bidirectional data bus, PWMX
output, SCIF and SSU control input/output, and interrupt input pins. The pin functions change
according to the operating mode. In addition, port 6 pins can also be used as the extended data bus
pins (D0 to D0). Port 6 has the following registers.
•
Port 6 data direction register (P6DDR)
•
Port 6 data register (P6DR)
•
Port 6 pull-up MOS control register (P6PCR)
(1)
Port 6 Data Direction Register (P6DDR)
The individual bits of P6DDR specify input or output for the pins of port 6.

If port 6 pins are specified for use as the general I/O
port, the corresponding pins function as output port
when the P6DDR bits are set to 1, and as input ports
when cleared to 0.

Normal extended mode (16-bit bus)
These bits have no effect on operation.
•
Other modes
If port 6 pins are specified for use as the general
I/O port, the corresponding pins function as output
port when the P6DDR bits are set to 1, and as
input port when cleared to 0.
