Title
Is the Bus-Hold feature in MAX 7000B devices active during JTAG Boundary Scan Testing (BST) and in-system programmability (ISP)?
Description
If the design pattern that is in the part specifies that a pin uses the Bus-Hold feature, the Bus-Hold feature will remain active during JTAG boundary scan testing.If the design pattern in the part does not specify that a pin uses the Bus-hold feature, then the Bus-Hold feature will not be active during JTAG boundary scan testing.
During ISP, the user's design pattern (which specifies which pins use the Bus-Hold feature) is being changed. Therefore, the Bus-Hold feature is disabled during ISP.
