Callin a C function from asm

Question

Hi everyone, 
 I am developing a software for a R2C114 in assembler langage but I 
 need to call C functions from my asm software. 
 Is it possible with the assembler I am using in HEW ? 
 R32C/100 Series Assembler system V.1.02.01 
 Thks in advance 
 Regards, 
 Jean-Pierre

The call of a C function without parameters and without return parameter is just a simple JSR to the function where in assembler the C function name in preceded by a '_'. 
If you want to pass parameters or receive a return parameter please refer to Appendix D.3 of the NC100 User's Manual.
