This bit controls whether the CPU[0] output buffer
is free-running or stoppable. If it is set to stoppable
the CPU[0] output buffer will be disabled with the
assertion of CPU_STP#.
This bit controls whether the CPU[1] output buffer
is free-running or stoppable. If it is set to stoppable
the CPU[1] output buffer will be disabled with the
assertion of CPU_STP#.
This bit controls whether the CPU[2] output buffer
is free-running or stoppable. If it is set to stoppable
the CPU[2] output buffer will be disabled with the
assertion of CPU_STP#.
