Port H Control Register (PHCR) is a 16-bit read/write register that selects the pin functions.
PHCR is initialized to H'AAAAA(ASEMD0 = 1) or H'8AAA (ASEMD0 = 0) by power-on resets;
however, it is not initialized by manual resets, in standby mode, or in sleep mode.
Bits 15, 14: PH7 Mode 1, 0 (PH7MD1, PH7MD0)
Bits 13, 12: PH6 Mode 1, 0 (PH6MD1, PH6MD0)
Bits 11, 10: PH5 Mode 1, 0 (PH5MD1, PH5MD0)
Bits 9, 8: PH4 Mode 1, 0 (PH4MD1, PH4MD0)
Bits 7, 6: PH3 Mode 1, 0 (PH3MD1, PH3MD0)
Bits 5, 4: PH2 Mode 1, 0 (PH2MD1, PH2MD0)
Bits 3, 2: PH1 Mode 1, 0 (PH1MD1, PH1MD0)
Bits 1, 0: PH0 Mode 1, 0 (PH0MD1, PH0MD0)
These bits select the pin functions and the input pullup MOS control.
