IEEE Std. 1149.1 JTAG State Names
The array variable, I_IDCODE, is initialized with the IDCODE
instruction bits ordered the LSB first (on the left) to most
significant bit (MSB) (on the right). This order is important
because the array field in the IRSCAN instruction is always
interpreted, and sent, MSB to LSB.
