5.32.16 Custom I/O Settings and Boundary Scan Registers
Each I/O in your device is comprised of an Input, Output and Output Enable Boundary Scan Register (BSR) cell..
The BSR cells enable you to define I/O states during programming and control the individual states for each Input, Output, and Output Enable register.
The Specify I/O States During Programming dialog box enables access to each of these BSR cells for control over the individual states. You can use the I/O State (Output Only) settings to set a specific output state and ignore the other values for the individual BSR elements, or you can click the Show BSR Details checkbox for control over the settings for each Input, Output Enable, and Output as you exit programming.
