Condition code suffixes

Conditional branch is shown in syntax descriptions as B{cond}. A branch instruction with a

condition code is only taken if the condition code flags in the APSR meet the specified

condition, otherwise the branch instruction is ignored. Table 18 shows the condition codes

to use.

Table 18 also shows the relationship between condition code suffixes and the N, Z, C, and V

flags

Table 18. Condition code suffixes

Suffix

Flags

Meaning

Z = 1

Equal, last flag setting result was zero.

Z = 0

Not equal, last flag setting result was non-zero.

CS or HS

C = 1

Higher or same, unsigned.

CC or LO

C = 0

Lower, unsigned.

N = 1

Negative.

N = 0

Positive or zero.

V = 1

Overflow.

V = 0

No overflow.

C = 1 and Z = 0

Higher, unsigned.

C = 0 or Z = 1

Lower or same, unsigned.

N = V

Greater than or equal, signed.

N != V

Less than, signed.

Z = 0 and N = V

Greater than, signed.

Z = 1 or N != V

Less than or equal, signed.

Can have any value

Always. This is the default when no suffix is specified.
