Compiler: v18.12.2.LTS

Tool/software: TI C/C++ Compiler

Hello All, 

My question is concerning 

• Arm® code generation tools - compiler, part number: ARM-CGT-18, version v18.12.2.LTS 

the question is: while I am using "Hex Conversion Utility" to generate a "Motorola-S" file format, I've used this command line "armhex --motorola=1 myOUT.out", the output of that line is 4 files (myOUT.m0, myOUT.m1, myOUT.m2 & myOUT.m3)

what are those files and their extensions ??!!!

I expected that the output would be just a ".srec" file 

How to generate an SREC file using that compiler ??

Thanks in advance.

Kind regards.
