I am attempting to set the configuration in an MPM3695-25.
I tried following the instructions on page 32 of the datasheet, but I am having trouble getting it to work.
The datasheet states to send the following command to set the MTP:
E7h(2000h) → E7h(1000h) → E7h(4000h)
I have done this and when a write with this 0xE7 command goes to the module, it doesn’t ACK.
Thank you for the quick response.
I am still unable to get this to work. The device does not ACK to the 0xE7 register address.
To be robust this is what I am attempting:
I didn’t understand that I had to apply a different voltage to it.
So, do I have to send the first erase command, then change the output voltage according to the chart with the VOUT_COMMAND register?
If so, how do I change VCC without changing VOUT, as this range would damage circuits downstream?
Is timing critical here? If so, what are the details of that?
