The MAX II device instruction register length is 10 bits and the USERCODE
register length is 32 bits.
register length and device IDCODE information for MAX II devices.
For JTAG AC characteristics, refer to the chapter on DC & Switching
Characteristics. For more information on JTAG BST, see the chapter on
IEEE 1149.1 (JTAG) Boundary-Scan Testing for MAX II Devices.
JTAG Translator
The JTAG translator feature allows you to access the JTAG TAP and state
signals when either the USER0 or USER1 instruction is issued to the JTAG
TAP. The USER0 and USER1 instructions bring the JTAG boundary scan
chain (TDI) through the user logic instead of the MAX II device’s
boundary scan cells. Each USER instruction allows for one unique user-
defined JTAG chain into the logic array.
