IEEE Std. 1149.1 BST Operation Control  
Figure 8–11 resembles the SAMPLE/PRELOADwaveform diagram, except that the  
instruction code for EXTESTis different. The data shifted out of TDOconsists of the data  
that was present in the capture registers after the capture phase. New test data shifted  
into the TDIpin appears at the TDOpin after being clocked through the entire  
boundary-scan register.

After boundry-scan  
register data has been  
shifted out, data  
entered into TDI will  
shift out of TDO.  
Data stored in  
boundary-scan  
register is shifted  
out of TDO.

BYPASS Instruction Mode  
You can activate BYPASSinstruction mode with an instruction code made up of only  
ones. Figure 8–12 shows how scan data passes through a device after the TAP  
controller is in the SHIFT_DRstate. In this state, data signals are clocked into the bypass  
register from TDIon the rising edge of TCKand out of TDOon the falling edge of the  
same clock pulse.

Instruction Code  
IDCODE Instruction Mode  
Use IDCODEinstruction mode to identify the devices in an IEEE Std. 1149.1 chain.  
When you select IDCODE, the device identification register loads with the 32-bit  
vendor-defined identification code. The device ID register is connected between the  
TDIand TDOports and the device IDCODEis shifted out.

IDCODEinstruction mode for MAX V devices are listed in the JTAG and In-System  
Programmability in MAX V Devices chapter.
