10.11.2 Port C Data Register (PCDR)
PCDR stores output data for the port C pins.
Bit Bit Name Initial Value R/W Description
7 PC7DR 0 R/W
6 PC6DR 0 R/W
5 PC5DR 0 R/W
4 PC4DR 0 R/W
3 PC3DR 0 R/W
2 PC2DR 0 R/W
1 PC1DR 0 R/W
0 PC0DR 0 R/W
Output data for a pin is stored when the pin function
is specified as a general purpose I/O.
10.11.3 Port C Register (PORTC)
PORTC shows the pin states of port C. PORTC cannot be modified.
Bit Bit Name Initial Value R/W Description
7 PC7 ⎯* R
6 PC6 ⎯* R
5 PC5 ⎯* R
4 PC4 ⎯* R
3 PC3 ⎯* R
2 PC2 ⎯* R
1 PC1 ⎯* R
0 PC0 ⎯* R
If this register is read while a PCDDR bit is set to 1,
the corresponding PCDR value is read. If this
register is read while a PCDDR bit is cleared to 0,
the corresponding pin state is read.
Note: * Determined by the states of pins PC7 to PC0.
