This register can be used to control trace features on some L2 implementations. Writing to
this register causes a store-like transaction on the L2 interface, with a TTYPE of
MTSPR_TRACE if the expression (CCR2[EN_TRACE] and (XUCR0[TRACE_UM] or not
MSR[PR])) = 1 for the executing thread. If the expression is false, the operation is treated
as a nop. The data written to this field is placed in the address on the L2 interface accord-
ing to the table below.
