BCR39: PCI DATA Register Two (DATA2) Alias
Register
Note:
This register is an alias of the DATA register and
also of the DATA_SCALE field of the PMCSR register.
Since these two are read only, BCR39 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
two. Bits 15-0 in this register are programmable
through the EEPROM.
