7.12
Port B is an 8-bit I/O port. Port B pins also have LPC input/output pins, and wakeup event
interrupt input pins function. Port B has the following registers.

PBDDR has the same address as P7PIN, and if
read, the port 7 pin states will be returned.
A port B pin becomes an output port if the
corresponding PBDDR bit is set to 1, and an input
port if the bit is cleared to 0.
PBODR can always be read or written to,
regardless of the contents of PBDDR.
