Memorypool Function
Can I use C language standard function "malloc" to allocate memory (variable-size) dynamically with the MR308?●   
Can system call of the variable-size memorypool function be issued from a handler (interrupt handler, cyclic handler, alarm
handler)?
●   
In the variable-size memorypool function, there are 4 types of memory block sizes available based on the value
(max_memsize) specified in the configuration file. Please let us know the equation for determining these 4 block sizes.

language to write the source file. (Mar. 20, 2001)
