Set IO Mask

Tools Supported: FastScan

Scope: All modes

Usage

SET IO Mask [OFf ON]

Description

Modifies the behavior of IO pins so that their expected values will always be X during test cycles in which the primary input portion of the IO pin is being forced.

Typically, when FastScan forces stimulus on an IO pin, it will expect to measure the same value on the corresponding PO. This command allows you to modify this behavior in cases where this is undesirable.

Arguments

OFf

An optional literal that disables the ability to mask the I/O pin output value. This is the default.

ON

An optional literal that enables the ability to mask the I/O pin output value.
