Operation Calculator

Initial Value (Reset Value)

1.	\|=	0x00000001	→ 0x00000001
2.	&=	~0x00000002	→ 0x00000001

Final Result

0x00000001

00000000 00000000 00000000 00000001

GENERATED CODE (C)

uint32_t reg = 0x00000000;
reg |= 0x00000001;
reg &= ~0x00000002;
// Final value: 0x00000001

📖 How to use Register Reset Calculator?

Register Reset Calculator lets you trace how a series of bitwise operations (|=, &=, ^=) modify a register value starting from its default state (Reset Value).

Enter the initial value (e.g. 0x00000000).
Select an operation (OR, AND, XOR, SET) and provide a mask, adding it with the Calculate button. Tilde (~) is supported, commonly used in bitwise coding (e.g. ~0x01).
You will get a step-by-step calculated current register state, final HEX/BIN value and ready-to-paste C code.
