This register is an alias of BCR38.
The contents of this register are cleared to 0 when the
RST pin is asserted, before the serial EEPROM is
read, and after a serial EEPROM read error.
Offset 1C0h
This register is identical to the PCI Data Register Zero
Alias Register except that it contains the data that ap-
pears in the DATA_SCALE field of the PCI Power Man-
agement Control/Status Register (PMCSR) and the
PCI Data Register when the DATA_SEL field of
PMCSR is set to 2.
This register is an alias of BCR39.
The contents of this register are cleared to 0 when the
RST pin is asserted, before the serial EEPROM is
read, and after a serial EEPROM read error.
Offset 1C2h
This register is identical to the PCI Data Register Zero
Alias Register except that it contains the data that ap-
pears in the DATA_SCALE field of the PCI Power Man-
agement Control/Status Register (PMCSR) and the
PCI Data Register when the DATA_SEL field of
PMCSR is set to 3.
This register is an alias of BCR40.
The contents of this register are cleared to 0 when the
RST pin is asserted, before the serial EEPROM is
read, and after a serial EEPROM read error.
Offset 1C4h
This register is identical to the PCI Data Register Zero
Alias Register except that it contains the data that ap-
pears in the DATA_SCALE field of the PCI Power Man-
agement Control/Status Register (PMCSR) and the
PCI Data Register when the DATA_SEL field of
PMCSR is set to 4.
This register is an alias of BCR41.

Offset 1C8h
This register is identical to the PCI Data Register Zero
Alias Register except that it contains the data that ap-
pears in the DATA_SCALE field of the PCI Power Man-
agement Control/Status Register (PMCSR) and the
PCI Data Register when the DATA_SEL field of
PMCSR is set to 6.
This register is an alias of BCR43.
The contents of this register are cleared to 0 when the
RST pin is asserted, before the serial EEPROM is
read, and after a serial EEPROM read error.
Offset 1CAh
This register is identical to the PCI Data Register Zero
Alias Register except that it contains the data that ap-
pears in the DATA_SCALE field of the PCI Power Man-
agement Control/Status Register (PMCSR) and the
PCI Data Register when the DATA_SEL field of
PMCSR is set to 7.
This register is an alias of BCR44.
The contents of this register are cleared to 0 when the
