Port 3 Data Direction Register (P3DDR)
P3DDR is an 8-bit write-dedicated register, which specifies the I/O for each port 3 pin by bit.
Read is disenabled. If a read is carried out, undefined values are read out.
By setting P3DDR to 1, the corresponding port 3 pins become output, and be clearing to 0 they
become input.
P3DDR is initialized to B'**000000 by a reset and in hardware standby mode. The previous state
is maintained in software standby mode. The pin state is determined by specifying SCI, IIC * ,
P3DDR, and P3DR.
Note: * Available when using I
