Hi there, I'm seeing some odd behaviour trying to program a blank MMPF0100 with the below config using KITPFGUI;
DEVICE:PF0100A

ADDR:DC:DATA:0F // VGEN6 VOUT
ADDR:DD:DATA:1F // VGEN6 SEQ
For some reason the bolded addresses are not programming properly, and when I do a verify I get the below;
Extracting OTP Data from Target Device...
Verifying OTP Data from Target Device...
OTP REG:[AD], DATA:[0x1C] = [0x1E] (PROGRAMMING ERROR)
OTP REG:[B6], DATA:[0x00] = [0x01] (PROGRAMMING ERROR)
OTP REG:[D0], DATA:[0x0F] = [0x0D] (PROGRAMMING ERROR)
OTP REG:[DD], DATA:[0x1F] = [0x1E] (PROGRAMMING ERROR)
Verification Complete. 5 Programming Errors
This has happened multiple times. I'm using the KITPFPGMEVME programmer and my own board with the PMIC loaded. I've double checked the I2C bus lines, the high voltage programming line etc and all look ok. And weirdly it seems to be these specific bits. One thing of note is that I am using the rail sequence slots at the end of the sequence - i.e. slots 26-31, rather than the ones at the beginning, to add some delay to the rail power up sequence. I usually use those at the beginning and have not seen this issue before. Your help would be much appreciated.
