Hello,
I have a question regarding the LP55231 power-up reset process.
Which one writes FF to the reset register (3Dh) when the EN pin is in "L" state or when the EN pin is in "H" state?
Please let me know your opinion as to which of the following A) or B) is correct for the startup procedure.
A)
EN pin: H
↓
Write FF to reset register

CHIP_EN: H
B)
Write FF to reset register
↓
EN pin: H
↓
CHIP_EN: H
Best regards,
