Notes:
1. Depending on the package, some input pads of the scan chain may not be connected to any external pin. In such case: LBO = 1, ZQ = 1,
PE = 0, SD = 0, ZZ = 0, FT = 1, DP = 1, and SCD = 1.
2. Every DQ pad consists of two scan registers—D is for input capture, and Q is for output capture.
3. A single register (#194) for controlling tristate of all the DQ pins is at the end of the scan chain (i.e., the last bit shifted in this tristate control
is effective after JTAG EXTEST instruction is executed.
4. 1 = no connect, internally set to logic value 1
5. 0 = no connect, internally set to logic value 0
6. X = no connect, value is undefined
