This definition is necessary to use Interrupt function.

The vector number can be written in the range of 0 to 63 and 247 to 255. However, whether or not the defined 
vector number is valid depends on the microcomputer used 

The relationship between interrupt causes and interrupt vector numbers for the M16C/80 series is shown in 
Table 6.3. 

Configurator can’t create an Initialize routine (interrupt control register, interrupt causes etc.) for this defined in-
terrupt. You need to create that.

[( Definition range )] 

YES or NO 

Define whether the handler is a kernel(OS dependent) interrupt handler. If it is a kernel(OS dependent) 
interrupt handler, specify YES; if it is a non-kernel(OS independent) interrupt handler, specify No. 

If this item is defined as YES, the declaration statement shown below is output to the kernel_id.h file. 

  

 

#pragma INTHANDLER /V4 function name 

If this item is defined as NO, the declaration statement shown below is output to the kernel_id.h file. 

 

 

#pragma INTERRUPT /V4 function name 

[( Definition format )]   

Symbol or function name 

[( Definition range )] None 

[( Default value )]   __SYS_DMY_INH 

Define the entry address of the interrupt handler. When written in the C language, add () at the end or 
at the beginning of the function name you have defined.

E, F, or B 

[( Default value )]   None 

Specify the switch to be passed to #pragma INTHANDLER or #pragma INTERRUPT. If "E" is specified, 
the "/E" switch is assumed, in which case multiple interrupts (another interrupt within an interrupt) are 
enabled. If "F" is specified, the "/F" switch is assumed, in which case the FREIT instruction is output at 
return from the interrupt handler. If "B" is specified, the "/B" switch is assumed, in which case register 
bank 1 is specified. 

Two or more switches can be specified at the same time. For kernel (OS dependent) interrupt han-
dlers, however, only the "E" switch can be specified. For non-kernel (OS independent) interrupt han-
dlers, the "E," "F," and "B" switches can be specified, subject to a limitation that "E" and "B" cannot be
