10.6 Port 6
Port 6 is a 6-bit I/O port that also has other functions. The port 6 has the following registers.
• Port 6 data direction register (P6DDR)
• Port 6 data register (P6DR)
• Port 6 register (PORT6)
10.6.1 Port 6 Data Direction Register (P6DDR)
The individual bits of P6DDR specify input or output for the pins of port 6.
P6DDR cannot be read; if it is, an undefined value will be read.
Bit Bit Name Initial Value R/W Description
7, 6 ⎯ All 0 ⎯ Reserved
5 P65DDR 0 W
4 P64DDR 0 W
3 P63DDR 0 W
2 P62DDR 0 W
1 P61DDR 0 W
When a pin function is specified to a general
purpose I/O, setting this bit to 1 makes the
corresponding port 1 pin an output pin, while
clearing this bit to 0 makes the pin an input pin.
0 P60DDR 0 W
