TXT Threads Join (Reserved) (TXT.THRDS.JOIN_R): This bit field
indicates the threads that have issued an SENTER-ACK cycle. Each bit
corresponds to a separate thread. When the chipset observes the SENTER-
ACK from the thread, it sets the corresponding bit in this register.
The format of the bits in this register is the same as in the
TXT.THREADS.EXISTS register.
The chipset will set the SENTER.DONE.STS bit when the
TXT.THREADS.EXISTS and TXT.THREADS.JOIN fields match and at least one
bit in the TXT.THREADS.EXISTS register is set.
When the chipset observes the SEXIT.ACK cycle, it will clear the
corresponding bit in this register. When it has cleared all the bits, it will set
SEXIT.DONE.
TXT Threads Join (TXT.THRDS.JOIN): This bit field indicates the threads
that have issued an SENTER-ACK cycle. Each bit corresponds to a separate
thread. When the chipset observes the SENTER-ACK from the thread, it sets
the corresponding bit in this register.
The format of the bits in this register is the same as in the
TXT.THREADS.EXISTS register.
The chipset will set the SENTER.DONE.STS bit when the
TXT.THREADS.EXISTS and TXT.THREADS.JOIN fields match and at least one
bit in the TXT.THREADS.EXISTS register is set.
When the chipset observes the SEXIT.ACK cycle, it will clear the
corresponding bit in this register. When it has cleared all the bits, it will set
SEXIT.DONE.
