Register Description:
The value of this register follows the same scheme as the device
identification register found in the IEEE 1149.1 specification. The upper four bits correspond to
silicon stepping. The next 16 bits store a Part ID Number. The next 11 bits contain a JEDEC
manufacturer ID. Bit zero = 1 if the chip is the first in a stack. The encoding scheme used for
the Product ID field is implementation-dependent.
