Syntax:

• IPUSHANDEQ Rs3 BS3 Rs0 Rs1

Description:

The IPUSHANDEQ operation is a single operation having the effect of an IPUSHEQ operation followed by an SAND operation. Explicitly, the logical operations are as follows:

Stack before IPUSHANDEQ:

High Condition	Low Condition
A	B	Top
C	D	Next

Stack after IPUSHANDEQ:

Bank Selector	Stack Item	High Condition	Low Condition
If Bs3 = 1 (low)	Top	([Rs0].L == [Rs1].L) & A	([Rs0].L == [Rs1].L) & B
	Next	C	D
If Bs3 = 2 (high)	Top	([Rs0].H == [Rs1].H) & A	([Rs0].H == [Rs1].H) & B
	Next	C	D
If Bs3 = 3 (vector)	Top	([Rs0].H == [Rs1].H) & A	([Rs0].L == [Rs1].L) & B
	Next	C	D

Note: [R].X denotes the data on bank X of register R and A, B, C, D take the values TRUE or FALSE.

Microcode Pattern:

Takes 5 cycles to execute.
