cpsr arm

What is the Cpsr in ARM?
The Linux/ARM embedded platform
ARM v6/v7 maintains a status register called the CPSR (current program status register) that holds four status bits, negative (N), zero (Z), carry (C), and overflow (O).
These bits can be used for conditional execution of subsequent instructions.
What is CPSR_c?
c = Control. x = eXtension. s = Status. f = Flags.
The purpose of using e.g.
CPSR_c is that it allows you to update only parts of the status register (in this case the control bits) without affecting the other parts.
What does Cpsr stand for?
Current Program Status Register (CPSR) Core Register Access.
The Current Program Status Register (CPSR) holds processor status and control information.
More
By manipulating the CPSR, you can control the execution of instructions and handle different processor modes.
The SPSR, on the other hand, allows you to save and restore the processor state when handling exceptions or interrupts.
