PM0044
STM8 instruction set
Doc ID 13590 Rev 3
123/162
Syntax
NEGW dst
e.g. NEGW X
Operation
dst <= (dst XOR FFFF) + 1, or 0000 - dst
Description
The destination word is read, then each bit is toggled (inverted), and the
result is incremented before it is written at the destination word. The
destination is an index register.
Instruction overview
.
V
⇒
R15.R14.R13.R12.R11.R10.R9.R8.R7.R6.R5.R4.R3.R2.R1.R0
Set if there is an arithmetic overflow on the 16-bit representation. The V bit
will set when the content of "dst" was $8000 prior to the NEGW operation,
cleared otherwise.
N
⇒
R15
Set if bit 7 of the result is set (negative value), cleared otherwise.
Z
⇒
R15.R14.R13.R12.R11.R10.R9.R8.R7.R6.R5.R4.R3.R2.R1.R0
Set if the result is zero (0x00), cleared otherwise.
C
⇒
R15+R14+R13+R12+R11+R10+R9+R8+R7+R6+R5+R4+R3+R2+R1+R0
Set if a borrow in the implied subtraction from zero, cleared otherwise. The
C bit will be set in all cases except when the contents of "dst" was $0000
prior to the NEGW operation.
