Another example may be an 8-bit register with the bit pattern 01010101 and the carry flag set; if we execute a rotate left through carry instruction, the result would be 10101011 with the carry flag cleared because the most significant bit (bit 7) was rotated into the carry while the carry was rotated into the least significant bit (bit 0).
the carry flag uses a "borrow bit" convention for subtracts, rather than the "carry bit" convention used by Microchip; they also include a signed overflow flag, which like the digit carry, is set by add, subtract and compare instructions (every instruction which sets the carry flag except for shift instructions);
Add-with-carry, with the overflow-flag EFLAGS.OF serving as carry input and output, with other flags left unchanged. SMAP Supervisor Mode Access Prevention. Repurposes the EFLAGS.AC (alignment check) flag to a flag that prevents access to user-mode memory while in ring 0, 1 or 2. CLAC: NP 0F 01 CA: Clear EFLAGS.AC. 0 Broadwell, Goldmont, Zen 1 ...
N Negative flag. Set to a copy of the most significant bit of an arithmetic result. V Overflow flag. Set in case of two's complement overflow. S Sign flag. Unique to AVR, this is always N⊕V, and shows the true sign of a comparison. H Half-carry flag. This is an internal carry from additions and is used to support BCD arithmetic. T Bit copy.
The Auxiliary Carry flag is set (to 1) if during an "add" operation there is a carry from the low nibble (lowest four bits) to the high nibble (upper four bits), or a borrow from the high nibble to the low nibble, in the low-order 8-bit portion, during a subtraction. Otherwise, if no such carry or borrow occurs, the flag is cleared or "reset ...
A status register, flag register, or condition code register (CCR) is a collection of status flag bits for a processor.Examples of such registers include FLAGS register in the x86 architecture, flags in the program status word (PSW) register in the IBM System/360 architecture through z/Architecture, and the application program status register (APSR) in the ARM Cortex-A architecture.
Typically these include a unit flag and a departmental flag (Army, Marines, Navy, Air Force, Space Force or Coast Guard, plus the National Guard Bureau (Army and/or Air Force)). In addition to the flag bearers, who are positioned in the center of the colour guard, there are two or more individuals who carry rifles and or sabres. This is a ...
In Cambodia, the Colours of the Military and other uniformed institutions follow British, US, and French practice.. Until 2022, what was essentially a large version of the Flag of Cambodia with the unit name below in white in the bottom blue stripe was used as the King's Colour of RCAF formations before being reassigned as the National Colour for parades and ceremonies.
