8.6
Port 6 is an 8-bit I/O port. Port 6 pins also function as the FRT input/output pin, keyboard input
pin, and noise cancel input pin. Port 6 functions change according to the operating mode. The port
can be used as the extended data bus (lower eight bits). Port 6 has the following registers.
• Port 6 data direction register (P6DDR)
• Port 6 data register (P6DR)
• Port 6 pull-up MOS control register (KMPCR6)
• System control register 2 (SYSCR2)
• Noise canceler enable register (P6NCE)
• Noise canceler decision control register (P6NCMC)
• Noise cancel cycle setting register (P6NCCS)
8.6.1
The individual bits of P6DDR specify input or output for the pins of port 6.

Description
Normal extended mode (16-bit data bus):
The port functions as the data bus regardless of the
values in these bits.
Other mode:
If port 6 pins are specified for use as the general I/O
port, the corresponding port 6 pins are output ports
when the P6DDR bits are set to 1, and input ports
when cleared to 0.
