respond to when receiving frames. Network addresses are generally expressed in the form of 01:23:45:67:89:AB,
where the bytes are received from left to right, and the bits within each byte are received right to left (LSB to MSB). The
actual transmitted and received bits are in the order of 10000000 11000100 10100010 11100110 10010001 11010101.

On-Chip Bus Control Register (Offset 0x0210): OBCR
This register controls the on-chip bus speed for the KSZ8842-PMQL/PMBL. It is used for reduced power consumption
when the external host CPU is running at a slow frequency. The default of the on-chip bus speed is 25MHz. When the
external host CPU is running at a higher clock rate, adjust the on-chip bus for the best performance.
The following table shows the register bit fields.

EEPROM Control Register (Offset 0x0212): EEPCR
KSZ8842-PMQL/PMBL supports designs with and without an EEPROM system design. To support an external
EEPROM, tie the EEPROM Enable (EEEN) pin/ball to High; otherwise, tie it to Low or no connect. The KSZ8842-
PMQL/PMBL allows 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 4 in EEPCR is set.
The following table shows the register bit fields.
