Cleared by H_RESET and is not
affected by S_RESET or setting
the STOP bit.
7-0
DATA3
These bits correspond to the PCI
DATA register (offset Register 47
of the PCI configuration space,
bits 7-0). Refer to the description
of DATA register for the meaning
of this field.
These bits are always read ac-
cessible. DATA3 is read only.
Cleared by H_RESET and is not
affected by S_RESET or setting
the STOP bit.
BCR41: PCI DATA Register 4 (DATA4) Alias Register
Note:
This register is an alias of the DATA register and
also of the DATA_SCALE field of the PCMCR register.
Since these two are read only, BCR41 provides a
means of programming them through the EEPROM.
The contents of this register are copied into the corre-
sponding fields pointed with the DATA_SEL field set to
four. Bits 15-0 in this register are programmable
through the EEPROM.

D4_SCALE
These bits correspond to the
DATA_SCALE field of the PMCSR
(offset register 44 of the PCI config-
uration space, bits 14-13). Refer to
the description of DATA_SCALE
for the meaning of this field.
Read
D4_SCALE is read only. Cleared
by H_RESET and is not affected
by S_RESET or setting the STOP
bit.

DATA4
These bits correspond to the PCI
DATA register (offset Register 47
of the PCI configuration space,
bits 7-0). Refer to the description
of DATA register for the meaning
of this field.

DATA4 is read only. Cleared by
H_RESET and is not affected
by S_RESET or setting the
STOP bit.

BCR42: PCI DATA Register 5 (DATA5) Alias Register
Note:
This register is an alias of the DATA register and
also of the DATA_SCALE field of the PCMCR register.
Since these two are read only, BCR42 provides a
means of programming them through the EEPROM.
The contents of this register are copied into the corre-
sponding fields pointed with the DATA_SEL field set to
five. Bits 15-0 in this register are programmable
through the EEPROM.

D5_SCALE
These bits correspond to the
DATA_SCALE field of the PMCSR
(offset Register 44 of the PCI con-
figuration space, bits 14-13). Refer
to the description of DATA_SCALE
for the meaning of this field.
These bits are always read ac-
cessible. D5_SCALE is read only.
Cleared by H_RESET and is not
affected by S_RESET or setting
the STOP bit.

DATA5
These bits correspond to the PCI
DATA register (offset Register 47
of the PCI configuration space,
bits 7-0). Refer to the description
of DATA register for the meaning
of this field.
These bits are always read ac-
cessible. DATA5 is read only.
Cleared by H_RESET and is not
affected by S_RESET or setting
the STOP bit.
BCR43: PCI DATA Register 6 (DATA6) Alias Register
Note:
This register is an alias of the DATA register and
also of the DATA_SCALE field of the PCMCR register.
Since these two are read only, BCR43 provides a
means of programming them through the EEPROM.
The contents of this register are copied into the corre-
sponding fields pointed with the DATA_SEL field set to
six. Bits 15-0 in this register are programmable through
the EEPROM.
