        6.1. Enabling BST Circuitry
The IEEE Std. 1149.1 BST circuitry is enabled after the device is configured. If you need to perform the boundary-scan test prior to configuration, you must execute the MISCCTRL instruction upon device power up to enable the BST circuitry.
MISCCTRL Instruction
!Shift 10-bit MISCCTRL instruction (0x013) to Instruction Register
SIR 10 TDI (013);  
!Transition to Run-Test-Idle state
STATE IDLE;        
!Shift 8-bit data (0x01) to Data Register for BST circuitry enabling
SDR 8 TDI (01);
