Set Request/Request Pending 7:0 RW 1S 0x0 Reading this field shall return a maximum of one
set bit at any time. The set bit shall point to the
lock owner. If the Mutex is not locked, a read
shall return a value 0x0000. Writing a 1 to the
already set bit shall relinquish the lock and the
set bit shall be cleared. Writing a 1 to an unset bit
shall cancel the corresponding pending request if
there was any–and the paring bit in the
Mutex_Request_Reg shall be cleared. Writing a
0 to any bits has no effect.
