Building the Sample Program

<R>

To check the operation of the sample program by using system simulator SM+ for 78K0S/Kx1+ (hereinafter referred

to as "SM+"), SM+ must be started after building the sample program. This section describes how to build a sample

program by using the assembly language sample program (source program + project file) downloaded by clicking the

[Column] Build errors

Change the compiler option setting according to the following procedure when the error message "A006 File

not found 'C:\NECTOOLS32\LIB78K0S\s0sl.rel'" or "*** ERROR F206 Segment '@@DATA' can't allocate to

memory - ignored." is displayed, when building with PM+.

A RAM area of 118 bytes that has been secured as a fixed standard library area will be enabled for use when

the [Using Fixed Area of Standard Library] check box is unchecked; however, the standard libraries (such as

the getchar function and malloc function) will be disabled for use.

The [Using Fixed Area of Standard Library] check box is unchecked by default when the file that has been
