Section 20 I/O Ports
20.7.2
PFDR is a 16-bit read-only register that stores port F data. Bits PF7DR to PF0DR correspond to
pins PF7/AN7/DA1 to PF0/AN0, respectively. The general input function of pins PF7 to PF0 is
enabled only when the A/D converter and D/A converter are halted.
Even if a value is written to PFDR, that 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. However,
PFDR should not be read when the A/D converter and D/A converter are operating. Table 20.12
summarizes PFDR read/write operations.
