Note: In this example, the value is set to the port C data register H (PCDRH) by the bit operation instruction. Since the

bit operation instruction performs the read modify write access, the port input level read for the unspecified bit is

(2) Creation of new test.abs

If a new load module (test.abs) has been created, it means that you’ve finished adding/modifying hardware setup

files successfully.

(3) Running the program

Try running the program after downloading the load module. (LED7 on the SH7670 CPU board lights up)
