8.2.4
P3ODR controls the PMOS on/off state for each port 3 pin.
8.2.5
Port 3 pins also function as SCI I/O pins and external interrupt input (IRQ4) pins. The
correspondence between the register specification and the pin functions is shown below. The P36
pin must be used as the D+ pull-up control output pin of the USB. For details, refer to section 14,
Universal Serial Bus (USB).

Setting a P3ODR bit to 1 makes the corresponding port 3
pin an NMOS open-drain output pin, while clearing the bit
to 0 makes the pin a CMOS output pin.
