7.11
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.
• Port B data direction register (PBDDR)
• Port B output data register (PBODR)
• Port B input data register (PBPIN)
7.11.1
PBDDR specifies input or output for the pins of port B on a bit-by-bit basis.
7.11.2
PBODR stores output data for port B.

Description
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.
Description
PBODR can always be read or written to, regardless of
the contents of PBDDR.
