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.
