Bits 19:16 – MCx [x=3..0]: Match or Capture x
This flag is set on the next CLK_TCC_COUNT cycle after a match with the compare condition or once CCx regis-
ter contain a valid capture value.
Writing a zero to one of these bits has no effect.
Writing a one to one of these bits will clear the corresponding Match or Capture Channel x interrupt flag
In Capture operation, this flag is automatically cleared when CCx register is read.
