Subject: [PATCH 0/4] rtc:abx80x: Enable distributed digital calibration
Date: Mon, 29 Mar 2021 00:02:28 +0300 [thread overview]
Message-ID: <20210328210232.10395-1-kirill.kapranov@compulab.co.il> (raw)
This patch series enables a Distributed Digital Calibration function for
the RTC of the family. This feature allows to improve the RTC accuracy by
means of compensation an XT oscillator drift. To learn more, see:
AB08XX Series Ultra Low Power RTC IC User's Guide
https://abracon.com/realtimeclock/AB08XX-Application-Manual.pdf
The patches 1 and 2 enable SQW output, that is necessary for subsequent
measurement and computation. However, this feature may be enabled and used
independently, as is.
The patches 3 and 4 enable the XT calibration feature per se. The SQW
output must be enabled for usage of this feature.
TIA!
Kirill
