Summary of Changes
1.0
1/16/09
Data sheet created.
1.1
10/13/09
Updated current consumption in Electrical Characteristics section.
Corrected data sheet omission of register 1 bit 8 for 1000Base-T Extended Status information.
Added the following register bits to provide further power saving during software power down: Tri-
state all digital I/Os (reg. 258.7), LDO disable (reg. 263.15), Low frequency oscillator mode (reg.
263.8).
Added KSZ9021RN device and updated entire data sheet accordingly.
Added 48-Pin QFN package information.
1.2
2/13/14
Added RGMII Pad Skew Registers section.
Corrected pad skew steps in Registers 260 (104h) and 261 (105h). Datasheet values are incorrect.
There is no change to the silicon.
Added Register 262 (106h) for RGMII TX Data Pad Skew.
Updated boilerplate.
