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 USERCODE register
length is 32 bits.

and
Places the 1-bit bypass register between the TDI and TDO pins,
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.
