4.2 The Condition Field
Figure 6: Condition Codes
All ARM60 instructions are conditionally executed, which means that their execution may or may not take
place depending on the values of the N, Z, C and V flags in the CPSR. The condition encoding is shown in
Figure 6: Condition Codes
.
If the
(NV) class of condition codes shall not be used as they will be redefined in future variants of the ARM
architecture. If a NOP is required it is suggested that MOV R0,R0 be used. The assembler treats the absence
of a condition code as though
always
had been specified.
always
(AL) condition is specified, the instruction will be executed irrespective of the flags. The
never
The other condition codes have meanings as detailed in
(EQual) causes the instruction to be executed only if the Z flag is set. This would correspond to the case
where a compare (CMP) instruction had found the two operands to be equal. If the two operands were
different, the compare instruction would have cleared the Z flag and the instruction will not be executed.

0000 = EQ - Z set (equal)
0001 = NE - Z clear (not equal)
0010 = CS - C set (unsigned higher or same)

1000 = HI - C set and Z clear (unsigned higher)
1001 = LS - C clear or Z set (unsigned lower or same)
1010 = GE - N set and V set, or N clear and V clear (greater or equal)
1011 = LT - N set and V clear, or N clear and V set (less than)
1100 = GT - Z clear, and either N set and V set, or N clear and V clear (greater than)
