(2) Port F Output Data Register (PFODR)
PFODR stores output data for the port F pins. PEODR is initialized only by a system reset, and
retains the value even if an internal reset signal of the WDT is generated.
Bit Bit Name Initial Value R/W Description
7    Reserved
Undefined value is read from this bit.
6 PF6ODR 0 R/W Stores the output data for the pin that is used as the
general output port.
5 to 2    Reserved
Undefined values are read from these bits.
1 PF1ODR 0 R/W
0 PF0ODR 0 R/W
Store the output data for the pins that are used as the
general output port.
(3) Port F Input Data Register (PFPIN)
PFPIN indicates the pin states of port F.
Bit Bit Name Initial Value R/W Description
7    Reserved
Undefined value is read from this bit.
6 PF6PIN Undefined* R When this register is read, the pin states are read.
Since this register is allocated to the same address as
PFDDR, writing to this register writes data to PFDDR
and the port F setting is changed.
5 to 2    Reserved
Undefined values are read from these bits.
1 PF1PIN Undefined* R
0 PF0PIN Undefined* R
When this register is read, the pin states are read.
Since this register is allocated to the same address as
PFDDR, writing to this register writes data to PFDDR
and the port F setting is changed.
Note: * The initial value of these pins is determined in accordance with the state of pins PF6,
PF1, and PF0.
