Set IE to input mode when using WAIT/BUSREQ input function.
In addition to above functions, a function of inputting and outputting the control and status signals of CPU is
provided. If the P30 pin is set to RD signal output mode (<P30F> = "1"), the RD strobe is output only when
an external address area is accessed. Likewise, if the P31 pin is set to WR signal output mode
(<P31F> = "1"), the WR strobe is output only when an external address area is accessed.
The port 3 is a general-purpose, 8-bit input/output port. For this port, inputs and outputs can be specified in
units of bits. Outputs can be set by using the control register P3CR and the function register P3FC1.
