Section 17 Pin Function Controller (PFC)
17.1.6 Port F Control Register (PFCR)
Port F Control Register (PFCR) is a 16-bit read/write register that selects the pin functions and the
input pull-up MOS control. PFCR is initialized to H'AAAA (in case of ASEMD0 = 1) or H'0000
(in case of ASEMD0 = 0) by power-on resets; however, it is not initialized by manual resets, in
standby mode, or in sleep mode.

When ASEMD0 = 0, this bit is always read as 0 and
must only be written with 0.
When ASEMD0 = 1, this bit is always read as 1 and
must only be written with 1.
