I would like to ask for clarification of the use of RESETN. On page 58 of SNAS663B (section 9.5.1) we are told to "Toggle RESETn pin High-Low-High" before programming. I have three related questions:
- How long does RESETN need to be held low in order to achieve a reliable reset? I have not managed to find this documented.
- How long is it necessary to wait after RESETN is driven high before programming the device? The documentation suggests no delay is required, but the linked question appears to suggest that a delay of 150ms may be required!
- If the power-up sequence has been correctly followed is there a compelling reason to apply the hardware reset?
