CALIBRATION OF TIMERS
may calibrate the internal timers using the calibration
command (refer to
receives the calibration command, the device expects 512 µs
logic [0] calibration pulse on the CS pin. The pulse is used to
calibrate the internal clock. No other SPI pins should
transition during this 512 µs calibration pulse. Because the
oscillator frequency changes with temperature, calibration is
required for an accurate time base. Calibrating the timers has
no affect on the quiescent current measurement. The
calibration command simply makes the time base more
accurate. The calibration command may be used to update
the device on a periodic basis.
