I'm Reading the c28x instruction set reference manual. Do someone know what the "RPT -" means ?

Hi, everyone

   I'm doing some c28x disassembling things right now. And I got the c28x instruction set reference manual -- spru430f.

   Then I went there, the ADD instruction section. I notice that there's "RPT" attribute followed every instruction, where

   I thought it means can be used after the "RPT" instruction to repeat itself. But why this "ADD ACC,loc16 <<T" instruction

   has CYCLE = N + 1, and "RPT -" the sametimes? Isn't It unrepeatable ? Can someone explain it to me ? Thnaks

    Hi,

    This looks like an erratum in the documentation. The "RPT" field for this instruction was added to the User's Guide on the last update and this got missed. This instruction is repeatable and takes "N+1" cycles when repeated. The flag behaviour after repeat is documented lower down on the same page you copied from.

    I will log this for correction in the next version. Thanks for pointing it out.

    Regards,

    Richard
