    Hi 
    

    I am using 21489 and find an interesting thing as follows:
    

     
    

    I defined "unsigned char abc = 456;" and used CCES to debug. I checked abc value in the window and i can find it is 456.
    

    I can not understand why abc can be more than 255? I thought i defined a unsigned char type value and it should be 0-255.
    

    Thanks.

      Hi,
      

      Please note that, unsigned char type value can be range between 0 - 4294967295 for the ADSP-21xxx Processors with no support for byte-addressing, or when using the -char-size-32 switch.
      

      You can refer the "Table 1. Representations of Integer Types on the ADSP-21xxx and ADSP-SCxxx Processors (with no support for byte-addressing, or when using the -char-size-32 switch)" in the below CCES help path for more details.
