QBIST Enable;
This bit is R/W and must stay high during QBIST. Changing
from 0 to 1 will reset bits 23:8 and 25.

Note:
QBIST will start once QBIST enable changes from 0 to 1 and stop when QBIST enable changes from1 to 0.
2:1) Bits 1 and 2 are exclusive of each other.
23:8) The error counter will wrap around once saturated. The user may check this counter against a timer to
determine the bit error rate.
8.2.11 JTAG Device ID Register
JTAG Device Identification register is provided for use with identifying the device. The content is duplicated here to

8.2.12 Case Scenario Configuration Registers
Case scenarios are used to generate sRIO outgoing packet headers when the SerB initiates a packet. In the case of
response packets, the incoming packet is used instead. A complete description is provided in the Case Scenario section.
These registers are read/write from any of the access ports. The default values are functionally don’t care, since they
cannot be used until programmed.
