Calibration Command
may calibrate the internal timers using the calibration
command (refer to
the calibration command, the device expects a 32µs logic[0]
calibration pulse on the CS pin. The pulse is used to calibrate
the internal clock. SPI communication is allowed during
calibration. Because the oscillator frequency changes with
temperature, calibration is required for an accurate time
base. The calibration command may be used to update the
device on a periodic basis.
