JTAG Instruction  
CLAMP(1)  
Instruction Code  
Description  
00 0000 1010  
Places the 1-bit bypass register between the TDIand TDOpins,  
which allows the boundary scan test data to pass synchronously  
through selected devices to adjacent devices during normal device  
operation, while holding I/O pins to a state defined by the data in the  
boundary-scan register.

This instruction allows you to define the scan chain between TDI  
and TDO in the MAX II logic array. This instruction is also used for  
custom logic and JTAG interfaces.

IEEE 1532  
instructions  
IEEE 1532 ISC instructions used when programming a MAX II device  
via the JTAG port.  
Notes to Table 3–1:  
(1) HIGHZ, CLAMP, and EXTESTinstructions do not disable weak pull-up resistors or bus hold features.  
(2) These instructions are shown in the 1532 BSDL files, which will be posted on the Altera® website at www.altera.com when they are available.  
w
Unsupported JTAG instructions should not be issued to the MAX II device as this may  
put the device into an unknown state, requiring a power cycle to recover device  
operation.  
The MAX II device instruction register length is 10 bits and the USERCODEregister  
length is 32 bits. Table 3–2 and Table 3–3 show the boundary-scan register length and  
device IDCODEinformation for MAX II devices.
