Writing a one to these bits will clear the corresponding bit in CHSR.
Writing a zero to these bits has no effect.
These bits always read a zero.
Warning: If the corresponding channel is disabled during a conversion or if it is disabled then reenabled during a conversion, its
associated data and its corresponding EOC and OVRE flags in SR are unpredictable.
