-| This is used for [[MCURTC:SetInfoLEDPattern|controlling]] the notification LED (see [[MCURTC:SetInfoLEDPatternHeader]] as well), when this register is written. It's possible to write data here with size less than 0x64, and only that portion of the pattern data will get overwritten. Reading from this register only returns zeroes, so it's considered write-only.
