■ Contained System Calls
The MB91302A-010's internal ROM contains the following system calls. During actual development,
register all of the following system calls using REALOS/FR's Configurator and be careful not to
any other system call.
The evaluation chip MB91V301A on the target board is used for debugging.
For how to register system calls using REALOS/FR Configurator, refer to the SOFTUNE REALOS/
FR Configurator Manual.
