Is the boundary scan length for EPM7032S and EPM7064S devices only 1?

Description

Yes, the boundary scan length for EPM7032S and EPM7064S devices in the MAX® 7000S family is only 1. 

 

Although EPM7032S and EPM7064S devices contain circuitry to support the Test Access Port (TAP) controller, these devices do not offer the Boundary Scan Cells (BSCs) required to support the EXTEST and SAMPLE/PRELOAD instructions. When the instruction register is updated with these instructions, the BYPASS register is selected. Therefore, you can place EPM7032S and EPM7064S devices in a chain of Boundary-Scan Test (BST) devices.
