What is Primask ARM?

What is the use of the Basepri register?
The special-purpose mask registers BASEPRI changes the priority level required for exception preemption. It has an effect only when BASEPRI has a lower value than the unmasked priority level of the currently executing software.
What is the use of Primask Faultmask and Basepri respectively?
The PRIMASK, FAULTMASK, and BASEPRI registers are used for exception or interrupt masking. The PRIMASK register is a 1-bit wide interrupt mask register. When set, it blocks all exceptions (including interrupts) apart from the Non-Maskable Interrupt (NMI) and the HardFault exception.

What is the purpose of register?
A processor register (CPU register) is one of a small set of data holding places that are part of the computer processor. A register may hold an instruction, a storage address, or any kind of data (such as a bit sequence or individual characters). Some instructions specify registers as part of the instruction.
How many registers are there?
The CPU has 8 general-purpose registers, each capable of storing 32-digit binary numbers.In addition to 32-bit data, they can also store 16- or 8-bit data. This is illustrated in Figure 4.2.
What are the types of register?
There are different types of registers, including memory address registers, memory buffer registers, input output address registers, and input output buffer registers and shift registers.
What is ARM microcontroller?
The Arm® Cortex®-M group of processor cores is a series of cores optimized for power efficiency and deterministic operation. It is widely used in microcontrollers (MCUs) and can also be found embedded into multi-core microprocessors (MPUs).
What is ARM register?
ARM processors provide general-purpose and special-purpose registers. Some additional registers are available in privileged execution modes. In all ARM processors, the following registers are available and accessible in any processor mode: 13 general-purpose registers R0-R12.
What is a special purpose register?
A Special Function Register (or Special Purpose Register, or simply Special Register) is a register within a microprocessor, which controls or monitors various aspects of the microprocessor's function.
What are 32 bit general-purpose registers?
General-Purpose Registers. The EAX, EDX, ECX, EBX, EBP, EDI, and ESI registers are 32-bit general-purpose registers, used for temporary data storage and memory access. The AX, DX, CX, BX, BP, DI, and SI registers are 16-bit equivalents of the above, they represent the low-order 16 bits of 32-bit registers.
What is priority mask register?
The priority mask is used to prevent interrupts from being sent to the MP11 CPU. The CPU Interface asserts an interrupt request to an MP11 CPU if the priority of the highest Pending interrupt sent by the Interrupt Distributor is strictly higher than the mask set in the Priority Mask Register.
What is the ECX register?
ECX register, an x86 general purpose register that is used by the CPU to store the loop counter. ECX screwdriver.
What is a program counter register?
A program counter is a register in a computer processor that contains the address (location) of the instruction being executed at the current time. As each instruction gets fetched, the program counter increases its stored value by 1.
What is the use of base registers and offset registers?
The base address register is a pointer to a byte in memory, and the offset specifies a number of bytes. Immediate means the address is calculated using the base address register and a 12-bit offset encoded in the instruction.
What is data register in computer?
In computer science, a data register is a special storage location within a CPU where data can be manipulated by the computer's arithmetic logic unit (ALU). The data register is one of the fundamental components of a CPU, and it is used to store temporary results during the execution of a program.
