Timer T12 Shadow Transfer Enable
Bit STE12 enables or disables the shadow transfer of
the T12 period value, the compare values and passive
state select bits and levels from their shadow registers
to the actual registers if a T12 shadow transfer event
is detected. Bit STE12 is cleared by hardware after the
shadow transfer.
A T12 shadow transfer event is a period-match while
counting up or a one-match while counting down.
