Hrm - actually, I can't do that. Unlike TCO1_STS, TCO2_STS and TCO1_CNT
registers that have some bits which are disabled by writing 1 to them
-- that's why I mask them out before updating -- the TCO_RLD and
TCO_TMR registers only have bits 15:10 marked as _reserved_ and I
should not zero them out. Does that seem correct to you?

Thanks,
