Port 6

Port 6 is an 8-bit I/O port. Port 6 pins also function as the interrupt input pin, TMR_Y, keyboard
and noise cancel input pins, FRT, and TMR_X input/output pin. Port 6 can change the input level
for four levels. Port 6 has the following registers.

• Port 6 data direction register (P6DDR)

• Port 6 data register (P6DR)
• Pull-up MOS control register (KMPCR)
• System control register 2 (SYSCR2)
• Noise canceller enable register (P6NCE)
• Noise canceller decision control register (P6NCMC)
• Noise cancel cycle setting register (P6NCCS)
