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.
