20.4.2
PFDR is a 16-bit read-only register that stores port F data. Bits PF1DR and PF0DR correspond to
pins PF1 and PF0, respectively.
Even if a value is written to PFDR, the value is not written into PFDR, and it does not affect the
pin state. If PFDR is read, the pin state, not the register value, is returned directly. Table 20.8
summarizes PFDR read/write operations.
