(2) Inputting CAL every V-sync
It is also possible to use only the startup calibration function by leaving the SEL pin (Pin 1/) low and fixing the
CAL pin (Pin 41) either high or low. Note that this method requires restriction of the fluctuation range of the
supply voltage and the reference voltage.
(4) Re-initiating the Startup Calibration Function
The startup calibration function can be re-initiated after the power and reference voltage are supplied by using
the CE pin (Pin 24) and the RESET pin (Pin 15). Particularly in cases where the riseup characteristics of the
power supply and the reference voltage are unstable or the order of the riseup is not kept, it is possible to
initiate startup calibration properly by connecting a CR and delaying startup until after power supply riseup.
