@ -438,6 +438,10 @@ The i.MXRT MCU supports battery backup of the RTC. By connecting a battery of
current drawn from the battery is ~20µA, which is rather high. A CR2032 coin
cell will last for about one year.
Note: In v1.23.0 the support for subseconds was removed. When reading the RTC, 0 will
be returned as value for subsecond, When setting the RTC time, the subsecond
field is ignored. The RTC itself does not provide a microsecond value.
