POP.D
Double Pop TOS to Wnd:Wnd+1
Implemented in: PIC24F PIC24H PIC24E dsPIC30F dsPIC33F dsPIC33E
X X X X X X
Syntax: {label:} POP.D Wnd
Operands: Wnd [W0, W2, W4, ... W14]
Operation: (W15) – 2 W15
(TOS) Wnd + 1
(W15) – 2 W15
(TOS) Wnd
Status Affected: None
Encoding:
1011 1110 0000 0ddd 0100 1111
Description: A double word is POPped from the Top-of-Stack (TOS) and stored to
Wnd:Wnd + 1. The most significant word is stored to Wnd + 1, and the
least significant word is stored to Wnd. Since a double word is POPped,
the Stack Pointer (W15) gets decremented by 4.
The ‘d’ bits select the address of the destination register pair.
Note 1: This instruction operates on double words. See Figure 4-3 for
information on how double words are aligned in memory.
2: Wnd must be an even working register.
3: This instruction is a specific version of the “MOV.D Ws, Wnd
instruction (MOV.D [--W15], Wnd). It reverse assembles as
MOV.D.
Words: 1
Cycles: 2
