Port B Control Register (PBCR) is a 16-bit read/write register that selects the pin functions. PBCR
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: PB7 Mode 1, 0 (PB7MD1, PB7MD0)
Bits 13, 12: PB6 Mode 1, 0 (PB6MD1, PB6MD0)
Bits 11, 10: PB5 Mode 1, 0 (PB5MD1, PB5MD0)
Bits 9, 8: PB4 Mode 1, 0 (PB4MD1, PB4MD0)
Bits 7, 6: PB3 Mode 1, 0 (PB3MD1, PB3MD0)
Bits 5, 4: PB2 Mode 1, 0 (PB2MD1, PB2MD0)
Bits 3, 2: PB1 Mode 1, 0 (PB1MD1, PB1MD0)
Bits 1, 0: PB0 Mode 1, 0 (PB0MD1, PB0MD0)
These bits select the pin functions and the input pullup MOS control.
