The XCHG instuction takes 6 states to execute.
Summary − So this instruction XCHG requires 1-Byte, 4-Machine Cycles (Opcode Fetch) and 4 T-States for execution as shown in the timing diagram.
xchg- Exchange contents of specified destination and source operands. eg. XCHG AL, CL Exchange contents of Al with CL XCHG BP, SI Exchange contents of BP with SI xlat- It is a translate instruction used for code conversion using look up table technique
XTHL instruction exchanges the contents of H-L register pair with the contents of the stack pointer (SP). SPHL instruction loads the HL register pair with the address contained in the stack pointer (SP), where SPHL = HL ← SP.
the salary cap for the sphl is like $1 million, so not alot
There is no STAX for HL register pair because the data transfer for STAX can be done through XCHG command. For ex: to transfer the data to the memory loaction specified by the HL pair we do as follows: XCHG STAX D for DE pair and BC pair we can directly do it using STAX
The Knoxville Ice Bears are in the Southern Professional Hockey League (SPHL) and have no direct affiliation with the NHL.

Professional hockey player, Daniel 'Scooter' Smith, was born in Calgary, Alberta, Canada on November 11, 1980. He played in the AHL, the ECHL, and the SPHL.
instruction register is used to store the next instruction to be executed. instruction pointer is used to store the address of the next instruction to be executed.
it is used as a temporary variable when the command XCHG is used, here two register values are xchanged with the help of this wz 16 bit register, this is not programmable.
