Appendix B: Virtual Configuration Register
1. The factory default value for the configuration register is 0x2102. This value is a
combination of the following: bit 13 = 0x2000, bit 8 = 0x0100, and bits 00 through
03 (see Table B-2) = 0x0002.

To avoid possibly hanging the CRBRIM-W/E, remember that valid
configuration register settings might be combinations of settings
and not just the individual settings listed in Table B-1. For
example, the factory default value of 0x2102 is a combination of
settings.
