Bank 3 EEPROM Control Register (0x02): EEPCR
To support an external EEPROM, tie the EEPROM Enable (EEEN) pin to High; otherwise, tie it to Low. If an external
EEPROM is not used, the default chip Base Address (0x300), and the software programs the host MAC address. If an
EEPROM is used in the design (EEPROM Enable pin to High), the chip Base Address and host MAC address are loaded
from the EEPROM immediately after reset. The KSZ8862M allows the software to access (read and write) the EEPROM
directly; that is, the EEPROM access timing can be fully controlled by the software if the EEPROM Software Access bit is
set.

Global Soft Reset
1: software reset is active.
0: software reset is inactive.
Software reset will affect PHY, MAC, QMU, DMA, and the switch core, only the BIU (base
address registers) remains unaffected by a software reset.
