The port B control register (PBCR) is a 16-bit readable/writable register that selects the pin
functions. PBCR is initialized to H'0000 by a power-on reset, but is not initialized by a manual
reset, in standby mode, or in sleep mode.
Bits 15 and 14—PB7 Mode 1 and 0 (PB7MD1, PB7MD0)
Bits 13 and 12—PB6 Mode 1 and 0 (PB6MD1, PB6MD0)
Bits 11 and 10—PB5 Mode 1 and 0 (PB5MD1, PB5MD0)
Bits 9 and 8—PB4 Mode 1 and 0 (PB4MD1, PB4MD0)
Bits 7 and 6—PB3 Mode 1 and 0 (PB3MD1, PB3MD0)
Bits 5 and 4—PB2 Mode 1 and 0 (PB2MD1, PB2MD0)
Bits 3 and 2—PB1 Mode 1 and 0 (PB1MD1, PB1MD0)
Bits 1 and 0—PB0 Mode 1 and 0 (PB0MD1, PB0MD0)
These bits select the pin functions and perform input pull-up MOS control.
