The command window can be closed by doing an IR scan, going to test logic reset, or by an ECL command. The ECL command is a subcommand of the STMC (opcode 0) command. The ECL command assumes the TAP state is starting from Pause DR.
When the command window is closed, the device TAP couples so any subsequent scans (IR or DR) are issued to the device TAP.
