Unlock MCU ATMEGA261A Heximal

We can Unlock MCU ATMEGA261A Heximal, please view the MCU ATMEGA261A features for your reference:

· Bit 5 – H: Half-carry Flag

The half-carry flag H indicates a half-carry in some arithmetic operations. See the Instruction Set description for detailed information when Unlock MCU Heximal.

· Bit 4 – S: Sign Bit, S = N V

The S-bit is always an exclusive or between the negative flag N and the two’s complement overflow flag V. See the Instruction Set description for detailed information if Unlock MCU Heximal.

· Bit 3 – V: Two’s Complement Overflow Flag

The two’s complement overflow flag V supports two’s complement arithmetics. See the Instruction Set description for detailed information before Unlock MCU Heximal.

· Bit 2 – N: Negative Flag

The negative flag N indicates a negative result after the different arithmetic and logic operations. See the Instruction Set description for detailed information after Unlock MCU Heximal.

· Bit 1 – Z: Zero Flag

The zero flag Z indicates a zero result after the different arithmetic and logic operations. See the Instruction Set description for detailed information when Unlock MCU Heximal.

· Bit 0 – C: Carry Flag

The carry flag C indicates a carry in an arithmetic or logic operation. See the Instruction Set description for detailed information if Unlock MCU Heximal.

The ATtiny15L provides eight interrupt sources. These interrupts and the separate reset vector each have a separate program vector in the program memory space before Unlock MCU Heximal.

All the interrupts are assigned individual enable bits that must be set (one) together with the I-bit in the status register in order to enable the interrupt.

The lowest addresses in the program memory space are automatically defined as the Reset and Interrupt vectors. The complete list of vectors is shown in Table 3 after Unlock MCU Heximal.

The list also determines the priority levels of the different interrupts. The lower the address the higher is the priority level. RESET has the highest priority, and next is INT0 (the External Interrupt Request 0), etc when Unlock MCU Heximal.
