Hello,
We are in the possession of fairly old datasheets (8 June 2015) of the LP873x . In these datasheets, the default power on delays for the different power supplies is 0 ms. This is of course a clear violation of the AM570x power sequency requirement.
There's an OTP to program default values to but for an initial power on, this OTP is empty.
1) Will the final LP873x PMICs contain correct default values for power-on sequence of the AM570x?
2) Is the OTP accessible by the user for programming? What would be the programming sequence?
3) Can you confirm that the I2C registers and/or OTP memory are accessible when the "EN" pin is not active? (for intial/factory programming of the OTP while the AM570x is powered off).
