I read this forum, but I’m still not entirely clear on how to configure the chip. Is it possible to configure it only once using OTP or is it possible to configure it again after each power-on without entering OTP? Or do you sell both variants with separate ordering codes? Thank You.
I think I understand now. Either I will have to set everything up again after each startup (by MCU), or I can write it down once using CTL_SYS18 D(7). Is that so?
Hi Vanfleet,
Thank you for posting to the MPS Technical Forum! You are correct about configuring the MPQ4242. You can configure the MPQ4242 with I2C after each power-on, but those register settings will reset back to the default when power-cycled. The OTP feature allows you to configure the registers as you’d like once, and then those settings will be retained through power cycles.
