When bit3 = 1, regardless of the direction register settings, the P45/SOUT2 and P46/SCLK2 pins function according to the serial I/O2 synchronous clock selection bit (bit6) as follows. Value obtained by reading port when direction register = 0 shown in ( ).
When bit6 = 0 : SOUT2 output pin ("1"), SCLK2 input pin (pin state)
When bit6 = 1 : SOUT2 output pin ("1" during data transfer, after transfer: pin state), SCLK2 output pin ("1")
When bit3 = 0, P45/SOUT2 pin is I/O port P45, and P46/SCLK2 pin is I/O port P46.
