In the CRIS v17 CPU an ADDC (add with carry) instruction has been added compared to the v10 instruction set. Assembler syntax: ADDC [Rs],Rd ADDC [Rs+],Rd Size: Dword Description: The source data is added together with the carry flag to the destination register. The size of the operation is dword. Operation: Rd += s + C-flag; Flags affected: S R P U I X N Z V C - - - - - 0 * * * * Instruction format: ADDC [Rs],Rd +---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+ |Destination(Rd)| 1 0 0 1 1 0 1 0 | Source(Rs) | +---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+ Instruction format: ADDC [Rs+],Rd +---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+ |Destination(Rd)| 1 1 0 1 1 0 1 0 | Source(Rs) | +---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+ [EI: Shorten 80+ lines] Reviewed-by: Edgar E.
