In-System Programming Clamp State logic option

A logic option that specifies the pin state during in-system programming. Unused pins and dedicated inputs must be set to Tri-state for in-system programming.

This option is useful for specifying voltage settings for individual pins. You can use the following settings: Tri-state, High, Low, or Sample and Sustain.

This option must be assigned to a pin or it is ignored.

This option is available for MAX® II devices.
