Revision ID is changed from ‘0x1555’ in Rev. A to ‘0x1556’ in Rev. A2. For customer software that needs to access the Revision ID information, software change might be needed. 2 For RMII 50MHz clock in mode, the hold time is now 2ns (min), compliant to RMII specification V1.2. In Rev. A, the required RMII hold time for the TXEN and TXD[1:0] inputs is 8ns (min). Applies to KSZ8021/8031/8051 devices that operate in RMII 50MHz clock in mode. 3 Fixed the issue with regard to the Re-start Autonegotiation bit. For Rev. A devices, after power-up, the Re-start Auto-negotiation bit (register 0, bit [9]) may fail to work properly to initialize the auto-negotiation state machine, resulting in link failure. The Re-start Auto-negotiation bit can be used in Rev. A2 now.
