Atmel ATA5771/73/74
SREG – AVR Status Register
• Bit 7 – I: Global Interrupt Enable
The Global Interrupt Enable bit must be set for the interrupts to be enabled. The individual
interrupt enable control is then performed in separate control registers. If the Global Interrupt
Enable Register is cleared, none of the interrupts are enabled independent of the individual
interrupt enable settings. The I-bit is cleared by hardware after an interrupt has occurred, and
is set by the RETI instruction to enable subsequent interrupts. The I-bit can also be set and
cleared by the application with the SEI and CLI instructions, as described in the instruction set
reference.
• Bit 6 – T: Bit Copy Storage
The Bit Copy instructions BLD (Bit LoaD) and BST (Bit STore) use the T-bit as source or des-
tination for the operated bit. A bit from a register in the Register File can be copied into T by
the BST instruction, and a bit in T can be copied into a bit in a register in the Register File by
the BLD instruction.
• Bit 5 – H: Half Carry Flag
The Half Carry Flag H indicates a Half Carry in some arithmetic operations. Half Carry is use-
ful in BCD arithmetic. See the “Instruction Set Description” for detailed information.
• Bit 4 – S: Sign Bit, S = N
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.
• 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.
• Bit 2 – N: Negative Flag
The Negative Flag N indicates a negative result in an arithmetic or logic operation. See the
“Instruction Set Description” for detailed information.
• Bit 1 – Z: Zero Flag
The Zero Flag Z indicates a zero result in an arithmetic or logic operation. See the “Instruction
Set Description” for detailed information.
• 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.
