Other Parts Discussed in Thread: TPS6521835, , TPS65218
Due to parts shortages on our Sitara platform, TI has offered the purchase of TPS6521835 and suggested to reprogram them as TPS65218D0. We use the PB line in our system for a manual reset with 8 second duration - this allows a customer to power cycle the system.
Is there any way to power cycle the system without resetting the register settings?
Also, to confirm, when a TPS6521835 is RESET, will the default values be returned to the TPS6521835 settings or to the TPS65218D0 settings. (I think I know the answer, but wanted to double check)
And a follow on question... most, but not all, registers are R/W. Are there some settings in the TPS6521835 that cannot be changed to TPS65218D0 values/functions? Does TI have any guidance or warnings as we embark down this river.
