Syntax:

• IPUSHLT Rs3 BS3 Rs0 Rs1

Description:

IPUSHLT pushes the following boolean conditions on top of the stack:

Bank Selector	High Condition	Low Condition
BS3 = 1 (low)	[Rs0].L < [Rs1].L	[Rs0].L < [Rs1].L
BS3 = 2 (high)	[Rs0].H < [Rs1].H	[Rs0].H < [Rs1].H
BS3 = 3 (vector)	[Rs0].H < [Rs1].H	[Rs0].L < [Rs1].L

Note: [R].X denotes the data on bank X of register R.

Microcode Pattern:

Takes 6 cycles to execute.
    Example: IPUSHLT 0xFF 3 0xA 0xB
