In the PIC/PID function, a program whose code or data in the ROM has been converted into PIC or PID is called an application, and the program necessary to execute an application is called the master.

The master executes the application initiation processing, and also provides the shared libraries called from applications and RAM areas for applications. PIC and PID are included only in applications; the master does not have them.

A group of functions in the master, which can be called from multiple applications.

A program through which applications can call shared libraries.
