Port 3 Open Drain Control Register (P3ODR)
P3ODR is an 8-bit readable/writable register, which controls the on/off of port 3 pins (P35 to P30).
By setting P3ODR to 1, the port 3 pins become an open drain out, and when cleared to 0 they
become CMOS output.
P3ODR is initialized to B'**000000 by a reset and in hardware standby mode. The previous state
is maintained in software standby mode.
9.3.3
The port 3 pins double as SCI I/O input pins (TxD0, RxD0, SCK0, TxD1, RxD1, and SCK1)
external interrupt input pins (IRQ4 and IRQ5), and IIC I/O pins * (SCL0, SDA0, SCL1, and
SDA1). The functions of port 3 pins are shown in table 9-5.
