Port A Control Register (PACR) is a 16-bit read/write register that selects the pin functions.
PACR is initialized to H'0000 by power-on resets; however, it is not initialized by manual resets,
in standby mode, or in sleep mode.
Bits 15, 14: PA7 Mode 1, 0 (PA7MD1, PA7MD0)
Bits 13, 12: PA6 Mode 1, 0 (PA6MD1, PA6MD0)
Bits 11, 10: PA5 Mode 1, 0 (PA5MD1, PA5MD0)
Bits 9, 8: PA4 Mode 1, 0 (PA4MD1, PA4MD0)
Bits 7, 6: PA3 Mode 1, 0 (PA3MD1, PA3MD0)
Bits 5, 4: PA2 Mode 1, 0 (PA2MD1, PA2MD0)
Bits 3, 2: PA1 Mode 1, 0 (PA1MD1, PA1MD0)
Bits 1, 0: PA0 Mode 1, 0 (PA0MD1, PA0MD0)
These bits select the pin functions and the input pullup MOS control.
