[( Definition format )] Symbol 

[( Definition range )] None 

[( Default value )]   MR_HEAP 

Define the name of the section in which the memory pool is located. The section defined here must 
always have an area allocated for it in the section file (asm_sec.inc or c_sec.inc).   

If no section names are defined, the memory pool is located in the MR_HEAP section. 

[( Definition format )] Numeric 

value 

[( Definition range )] 

16 to 0xFFFFFFFF 

[( Default value )]   None 

Specify a memory pool size. 

Round off a block size you specify to the optimal block size among the four block sizes, and acquires 
memory having the rounded-off size from the memory pool. 

The following equations define the block sizes: 

a = (((max_memsize+(X-1))/ (X 

× 8))+1) × 8 

b = a 

× 2 

c = a 

× 4 

d = a 

× 8 

 
max_memsize: the value specified in the configuration file 
X: data size for block control (8 byte per a block control) 

Variable-size memory pool function needs 8 byte RAM area per a block control. Memory pool size 
needs a size more than a, b, c or d that can be stored max_memsize + 8.

This definition is necessary to use Cyclic handler function.
