Serial-bus data. This signal is used as serial bus data when a pullup is detected on
SDA or when the SBDETECT bit is set in the serial bus control and status register.

I
Beta mode. This terminal determines the PHY-section/LLC-section interface
connection protocol. When logic high (asserted), the PHY-section/LLC-section
interface complies with the IEEE Std 1394b-2002 Revision 1.33 beta interface.
When logic low (deasserted), the PHY-section/LLC-section interface complies with
legacy IEEE Std 1394a-2000. This terminal must be pulled high with a 1-k
connection protocol. When logic high (asserted), the PHY-section/LLC-section
interface complies with the IEEE Std 1394b-2002 Revision 1.33 beta interface.
When logic low (deasserted), the PHY-section/LLC-section interface complies with
legacy IEEE Std 1394a-2000. This terminal must be pulled high with a 1-k

I
Voltage regulator power-down input. When asserted logic high, this pin will power-
down the internal 3.3- to 1.95V regulator. For single 3.3V supply operation, this pin
should be tied to GND. When using the internal regulator, the XIO2213B can
support a maximum of 2-Beta and 1-DS connection simultaneously. If 3-Beta ports
are required to be simultaneously supported, it is recommended to use an external
1.95V regulator.
