BCR42: PCI DATA Register Five (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
Reserved locations. Written as
zeros and read as undefined.
DATA_SCALE field of the PMC-
SR (offset register 44 of the PCI
configuration space, bits 14-13).
Refer
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
These bits correspond to the PCI
DATA register (offset Register 47
