Will the behavior of the DS3231 be affected if I write a "1" in CRATE0 and CRATE1 bits in register 0Fh?

Question

Accepted Answer

There is no logic behind those particular bits, so if you write them to a 1, there is no functional change to the RTC.

The bits should hold that 1 setting until the DS3231 is POR’d, at which time the power on default value of 0’s will be loaded into those bits.
