PUSHUD — Push User Stack (Decrementing)

PUSHUD	dst,src
Operation:	IR ← IR – 1
	dst ← src
	This instruction is used to address user-defined stacks in the register file. PUSHUD decrements the
	user stack pointer and loads the contents of the source into the register addressed by the
	decremented stack pointer.

Flags: No flags are affected.

Format:

opc	dst	src

Bytes	Cycles	Opcode	Addr Mode
		(Hex)	dst	src
3	8	82	IR	R

Example: Given: Register 00H = 03H, register 01H = 05H, and register 02H = 1AH:

PUSHUD @00H,01H →	Register 00H	=	02H, register 01H = 05H,
	register 02H	=	05H

If the user stack pointer (the register 00H, for example) contains the value 03H, the statement "PUSHUD @00H,01H" decrements the user stack pointer by one, leaving the value 02H.

The 01H register value, 05H, is then loaded into the register addressed by the decremented user stack pointer.
