Here, you will create a program that outputs a low-level signal from pin P14 of the
microcomputer to turn on LED5. Figure 2.8 shows the flow of the program. In the
flow, a value is set in the PDR1 register first, and then output setting is made using the
DDR1 register. For port output, be sure to set the output level in the PDR1 register
before the output setting using the DDR1 register. The setting operation should be
performed in this order because the initial value that is applied after the microcomputer is
reset is not defined for the PDR1 register (to set the output level).
Let us now create the actual program.
Appendix A.1, open the source file "main.c" stored in ”sample.prj”, and input the program
portion enclosed by dotted line in Figure 2.9. Use the files other than "main.c" without
modification.
procedure described in Appendix A.2. If an error message is output, check that the
content of the input program is exactly the same as the description shown in Figure 2.9.
When the build operation ends successfully, ACCEMIC MDE starts automatically.
For how to execute the program, see Appendix B.1. While the program is executed,
you can see that LED5 goes on on the board.
After the ACCEMIC MDE window appears, execute the program and check its operation.

After the input of the program, build the program according to the
Set P14 output level to low (PDR1.bit4=0).
