8.6 Port 6
Port 6 is a 4-bit I/O port. 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)
8.6.1 Port 6 Data Direction Register (P6DDR)
The individual bits of P6DDR specify input or output for the pins of port 6.
Bit Bit Name Initial Value R/W Description
7 ⎯ 0 W
6 ⎯ 0 W
5 ⎯ 0 W
4 ⎯ 0 W
Reserved
3 P63DDR 0 W
2 P62DDR 0 W
1 P61DDR 0 W
0 P60DDR 0 W
If port 6 pins are specified for use as the general I/O
port, the corresponding port 6 pins function as output
port when the P6DDR bits are set to 1, and as input
ports when cleared to 0.
