PROGRAM TRANSFER INSTRUCTIONS
Conditional Transfers — jump if:
JE/JZ= equal/zero
JL/JNGE = less/not greater or equal
JLE/JNG = less or equal/not greater
JB/JNAE = below/not above or equal
JC = carry
JBE/JNA = below or equal/not above
JP/JPE = parity/parity even
JO = overflow
JS = sign
JNE/JNZ = not equal/not zero
JNL/JGE = not less/greater or equal
JNLE/JG = not less or equal/greater
JNB/JAE = not below/above or equal
JNC = not carry
JNBE/JA = not below or equal/above
JNP/JPO = not parity/parity odd
JNO = not overflow
JNS = not sign
Unconditional Transfers
CALL = Call procedure
direct within segment
reg/memory indirect within segment
indirect intersegment
direct intersegment
NOTES:
1.
Clock cycles are given for 8-bit/16-bit operations.
2.
Clock cycles are given for jump not taken/jump taken.
3.
Clock cycles are given for interrupt taken/interrupt not taken.
4.
If TEST = 0
Shading indicates additions and enhancements to the 8086/8088 instruction set. See Appendix A, "80C186
