Set the internal TAP Controller Instruction Register (IR) by transitioning to Shift-IR from Test-Logic-Reset with 010100000 on bscan_ext_tdi, and then shifting in the 5-bit IR value (0x10 for dtmcs or 0x11 for dmi) on bscan_ext_tdi. Then transition to Update-IR from Shift-IR with 011 010 on bscan_ext_tdi.

Shift data to the internal TAP Controller by transitioning to Shift-DR from Update-IR via Capture-DR with 0100000 on tdi, and then shifting in the new 32-bit register value on bscan_ext_tdi, simultaneously with capturing the old register value on bscan_ext_tdo. Then transition from Shift-DR to Update-DR with 010 on bscan_ext_tdi, and finally transition back to Idle with 01000 on bscan_ext_tdi.
