Describe the process control instructions

STC - It sets the carry flag & does not affect any other flag 

CLC - it resets the carry flag to zero &does not affect any other flag

CMC - It complements the carry flag & does not affect any other flag

STD - It sets the direction flag to 1 so that SI and/or DI can be decremented automatically after implementation of string instruction & does not affect other flags

CLD - It resets the direction flag to 0 so that SI and/or DI can be increased automatically after implementation of string instruction & does not affect other flags

STI - Sets the interrupt flag to 1. Enables INTR of 8086.

CLI - Resets the interrupt flagto0. 8086 will not respond to INTR.
