In compare mode, the registers CC6xR (x=0,1,2) are the actual compare registers for
T12. The values stored in CC6xR are compared (all three channels in parallel) to the
counter value of T12. In capture mode, the current value of the T12 counter register is
captured by registers CC6xR if the corresponding capture event is detected.
The registers CC6xR can only be read by SW, the modification of the value is done by
a shadow register transfer from register CC6xSR. The corresponding shadow registers
CC6xSR can be read and written by SW. In capture mode, the value of the T12 counter
register can also be captured by registers CC6xSR if the selected capture event is
detected (depending on the selected mode).

In compare mode, the bitfields contents of CC6xS
are transferred to the bitfields CC6xV during a
shadow transfer. In capture mode, the captured
value of T12 can be read from these registers.
