10.14.2 Port F Data Register (PFDR)
PFDR stores output data for the port F pins.
Bit Bit Name Initial Value R/W Description
7 PF7DR 0 R/W
6 PF6DR 0 R/W
5 PF5DR 0 R/W
4 PF4DR 0 R/W
3 PF3DR 0 R/W
2 PF2DR 0 R/W
1 PF1DR 0 R/W
0 PF0DR 0 R/W
Output data for a pin is stored when the pin function
is specified as a general purpose I/O.
10.14.3 Port F Register (PORTF)
PORTF shows the pin states of port F. PORTF cannot be modified.
Bit Bit Name Initial Value R/W Description
7 PF7 ⎯* R
6 PF6 ⎯* R
5 PF5 ⎯* R
4 PF4 ⎯* R
3 PF3 ⎯* R
2 PF2 ⎯* R
1 PF1 ⎯* R
0 PF0 ⎯* R
If this register is read while a PFDDR bit is set to 1,
the corresponding PFDR value is read. If this
register is read while a PFDDR bit is cleared to 0,
the corresponding pin state is read.
Note: * Determined by the states of pins PF7 to PF0.
