7.7
Port 6 is an 8-bit I/O port. Port 6 pins also function as bidirectional data bus, SCI_2 I/O pins,
FRT_1 I/O pins, and TMRX_1 and TMRY_1 output pins. Port 6 functions change according to
the operating mode.
Port 6 has the following registers.
• Port 6 data direction register (P6DDR)
• Port 6 data register (P6DR)
• Port 6 register (PORT6)
• Port 6 pull-up MOS control register (P6PCR)
• Port 6 open-drain control register (P6ODR)
7.7.1
The individual bits in P6DDR specify input or output for the pins of port 6. The read value is
undefined.

In normal extended mode (16-bit data bus)
Operation is not affected.
In normal extended mode (8-bit data
bus)/multiplex extended mode
Operates as single-chip mode
In single-chip mode
While a general I/O port function is selected, the
corresponding port 6 pin is an output port when
a P6DDR bit is set to 1, and an input port when
cleared to 0.
