Instruction Code
The Quartus II software has an Auto Usercode feature where you can
choose to use the checksum value of a programming file as the JTAG user
code. If selected, the checksum is automatically loaded to the USERCODE
register. In the Settings dialog box in the Assignments menu, click Device
& Pin Options, then General, and then turn on the Auto Usercode
option.
Allows configuration of I/O standards through the JTAG chain for
JTAG testing. Can be executed before, after, or during
configuration. Stops configuration if executed during configuration.
Once issued, the

device is reconfigured.
Monitors internal device operation with the SignalTap II embedded
logic analyzer.
