Q - Saturation flag
V - Overflow flag
N - Negative flag
Z - Zero flag
C - Carry flag
System registers
This bit is not set or cleared implicit by any instruction and the programmer can therefore use
this bit as a custom flag to for example signal events in the program. This bit is cleared at reset.
Used by the conditional store instruction. Used to support atomical memory access. Automati-
cally cleared by rete. This bit is cleared after reset.
The saturation flag indicates that a saturating arithmetic operation overflowed. The flag is sticky
and once set it has to be manually cleared by a csrf instruction after the desired action has been
taken. See the Instruction set description for details.
The overflow flag indicates that an arithmetic operation overflowed. See the Instruction set
description for details.
The negative flag is modified by arithmetical and logical operations. See the Instruction set
description for details.
The zero flag indicates a zero result after an arithmetic or logic operation. See the Instruction set
description for details.
The carry flag indicates a carry after an arithmetic or logic operation. See the Instruction set
description for details.
The system registers are placed outside of the virtual memory space, and are only accessible
using the privileged mfsr and mtsr instructions. Some of the System Registers can be altered
automatically by hardware. The table below lists the system registers specified in AVR32UC.
The programmer is responsible for maintaining correct sequencing of any instructions following
a mtsr instruction.
