7. When it is converted from RI78V4 V1.00.02 to RI78V4 V2.00.00

The change point when converting from RI78V4 V1.00.02 application to RI78V4 V2.00.00 application is shown in the

following.

When a project of application with RI78V4 V1.00.02 is created by CubeSuite+ (CS+), if the project of application with

the RI78V4 V1.00.02 reads in the environment installed RI78V4 V2.00.00, the possible part changes a change

automatically.

7.1. The timer interrupt handler

The user has to describe the

“timer interrupt handler” in RI78V4 V1.00.02, it is not necessary to describe in V2.00.00.

Therefore you delete the timer interrupt handler, and specifies the clock timer exception code (CLK_INTNO) in the

system configuration file.

■ V1.00.02

[ C source file ]

#pragma rtos_interrupt INTP0 timer

void

timer(void){

TimerHandler();

return;

}

■ V2.00.00

[ System configuration file ]

CLK_INTNO ( INTTM00 );

Then CS+ is to read a project of application with RI78V4 V1.00.02, and a system configuration file is converted. But a

comment is being output by configurator so that this item may be designated because used timer interrupt cannot be

specified for this item,
