Please let me know about time until UCD9246 starts. Although not indicated to a data sheet,
---------------------------・Ready of OSC ・Release of PowerOn Reset ・CPU reads ROM Code. ・Initialization of Flash ---------------------------
I think that it will start after their times.
When the idea is right,
-------------------------CPU reads ROM Code. Initialization of Flash -------------------------
Please let me know their times.
Or although started in 30 ms now, is this a Min value or is it and a Max value?
I would appreciate your favor instruction .
The UCD92xx controllers runs through an initialization procedure after the V33 rails have reached their UVLO levels, the process takes ~15ms +/- a few ms (it is not defined in the spec). It would be done well within 30ms of reaching UVLO settings.
Upon completion of the initialization the rails will be available based upon their ON_OFF_CONFIG, VIN_ON, TON_DELAY and TON_RISE settings.
