ST10F166
Immediate data: these data are represented in the instruction formats by either 3,4,8
or 16 bits.
Branch target addressing modes: to specify the destination address and segment
of jump or call instructions, relative, absolute and indirect modes can be used to up-
date the Instruction Pointer (IP) register while the Code Segment Pointer (CSP) reg-
ister can be updated only with absolute values.
Condition Flags:
The condition flags of the PSW register (N,C,V,Z,E) indicate the ALU status due to
the last performed ALU operation. They are set by most of the instructions due to spe-
cific rules which depend on the ALU or data movement operation performed by an in-
struction. If the PSW register is the destination operand of an instruction, the PSW
flags do NOT represent the condition flags of this instruction as usual.
E: End of a table in a table search operation
Z: Zero
V: Overflow
C: Carry
N: Negative
