SIGNAL DESCRIPTION

ZAY ZAJ

TYPE

PACKAGE PACKAGE

SDA H12 H11 I/O 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.

Note: In serial-bus mode, an external pullup resistor is required to prevent the SDA

signal from floating.

BMODE A05 B06 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-kΩ resistor

during normal operation.

TESTM B02 A03 I Test control. This input is used in the manufacturing test of the XIO2213B. For

normal use, this terminal must be pulled high through a 1-kΩ resistor to V

VREG_PD A06 B07 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.

SE P13 M10 I Test control. This input is used in the manufacturing test of the XIO2213B. For

normal use, this terminal must be pulled low either through a 1-kΩ resistor to GND

or directly to GND.

SM P14 N10 I Test control. This input is used in the manufacturing test of the XIO2213B. For

normal use, this terminal must be pulled low either through a 1-kΩ resistor to GND

or directly to GND.
