Forms  pop    1 byte · 10 cycles 
The memory location pointed to by SP is stored into the low byte of rr and SP is incremented. The memory location pointed to by SP is stored into the high byte of rr and SP is incremented again.
 pop    2 bytes · 14 cycles 
The memory location pointed to by SP is stored into IXL and SP is incremented. The memory location pointed to by SP is stored into IXH and SP is incremented again.
Operands rr A register pair: bc, de, hl or af. 
ix The ix index register. You can also use iy, with the same instruction size and timing. More
