Preserve variable across soft reset in RX231

Question

Hi, Could anyone please show me an example how to reach that a variable will be preserved after a software reset in RX231 MCU. I could not yet figure out how to define and manage such a section. 
 Thanks, best regards

Seems I could figure it out finally, that's what I did:

#pragma section preserve 
 WHATEVER_t Whatever; //variable to be preserved 
 #pragma section 
 In addition the section had to be added in "MYPROJECT > Properties > C/C++Build > Linker > Section" as follows: 
 There may be nicer and more scientific solutions, but it works for me. best regards - gebild
