Consequently, the SHL EAX, CL instruction needs to execute the three micro-ops flow in subsequent iterations. The SUB instruction will update all flags. So replacing DEC with SUB will allow SHL EAX, CL to execute the two micro-ops flow. Terminology

Which flag is not affected by the DCR B instruction in 8085?

NettetCorrect option is C) DC x rp instructions will never affect the zero flag. The zero flag is a single bit flag that is a central feature on most conventional CPU architectures. It is often stored in a dedicated register, typically called status register or flag register, along with other flags. Was this answer helpful?
