Why do EPM7032S and EPM7064S devices have a boundary-scan length of one?

Environment

BUILT IN - ARTICLE INTRO SECOND COMPONENT
Description Although EPM7032S and EPM7064S devices contain circuitry to support the 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 even though they have a boundary-scan length of one.
