MAX V devices implement the SAMPLE/PRELOAD, EXTEST, BYPASS, IDCODE, USERCODE,
CLAMP and HIGHZ IEEE Std. 1149.1 BST instructions. The length of the BST instructions
is 10 bits. These instructions are described in detail later in this chapter.
For a summary of the BST instructions and their instruction codes, refer to the
and In-System Programmability in MAX V Devices
The IEEE Std. 1149.1 TAP controller, a 16-state state machine clocked on the rising
edge of TCK, uses the TMS pin to control IEEE Std. 1149.1 operation in the device.
