Timer T12 Run Bit
T12R starts and stops timer T12. It is set/reset by
software by setting bits T12RS or T12RR, or it is reset
by hardware according to the function defined by bit
field T12SSC.
0
Timer T12 is stopped.
1
Timer T12 is running.
A concurrent set/reset action on T12R (from T12SSC,
T12RR or T12RS) will have no effect. The bit T12R will
remain unchanged.
