Description
MSR Data 1. Most significant 32-bits of MSR data. DATA0 and DATA1 R/W are atomic in
nature (i.e., if DATA0 access is made in GLPCI_SB then it must followed by DATA1
access). Until the DATA1 access, GLPCI_SB will retry all other transactions on PCI bus
for 2
transactions are accepted.
15
cycles. After this timeout, atomic nature for DATA0 and DATA1 expires and other
