10.6.2  Port 6 Data Register (P6DR) 
P6DR stores output data for the port 6 pins. 
Bit  Bit Name  Initial Value  R/W  Description 
7, 6  ⎯ All 0 ⎯ Reserved 
These bits are always read as 0 and cannot be 
modified. 
5 P65DR  0  R/W 
4 P64DR  0  R/W 
3 P63DR  0  R/W 
2 P62DR  0  R/W 
1 P61DR  0  R/W 
0 P60DR  0  R/W 
Output data for a pin is stored when the pin function 
is specified as a general purpose I/O. 
10.6.3  Port 6 Register (PORT6) 
PORT6 shows the pin states of port 6. PORT6 cannot be modified. 
Bit  Bit Name  Initial Value  R/W  Description 
7, 6  ⎯ Undefined ⎯ Reserved 
If these bits are read, they will return an undefined 
value. 
5 P65  ⎯* R 
4 P64  ⎯* R 
3 P63  ⎯* R 
2 P62  ⎯* R 
1 P61  ⎯* R 
0 P60  ⎯* R 
If this register is read while a P6DDR bit is set to 1, 
the corresponding P6DR value is read. If this 
register is read while a P6DDR bit is cleared to 0, 
the corresponding pin state is read. 
Note:  *  Determined by the states of pins P65 to P60.
