The port F control register (PFCR) is a 16-bit readable/writable register that selects the pin
functions. PFCR is initialized to H'AAAA (ASEMD0 = 1) or H'00AA (ASEMD0 = 0) by a power-
on reset, but is not initialized by a manual reset, in standby mode, or in sleep mode.
Bits 15 and 14—PF7 Mode 1 and 0 (PF7MD1, PF7MD0)
Bits 13 and 12—PF6 Mode 1 and 0 (PF6MD1, PF6MD0)
Bits 11 and 10—PF5 Mode 1 and 0 (PF5MD1, PF5MD0)
Bits 9 and 8—PF4 Mode 1 and 0 (PF4MD1, PF4MD0)
Bits 7 and 6—PF3 Mode 1 and 0 (PF3MD1, PF3MD0)
Bits 5 and 4—PF2 Mode 1 and 0 (PF2MD1, PF2MD0)
Bits 3 and 2—PF1 Mode 1 and 0 (PF1MD1, PF1MD0)
Bits 1 and 0—PF0 Mode 1 and 0 (PF0MD1, PF0MD0)
These bits select the pin functions and perform input pull-up MOS control.
