I'm working on a project that uses the 6 I/O pins inthe ATtini85.
The problem is that sometimes I need to write some EEPROM values externally with an HVSP.
I'm trying to do it using a Raspberry, but I can't write to the EEPROM.
I can read and write fuses, lockbits, and I can read the EEPROM. But when I try to write to the EEPROM it only stores garbage.
I've followed all the steps printed in the datasheet, but it doesn't work.
Does anyone know if there is anything that isn't in the datasheet and is needed for writing to the EEPROM in HVSP mode?
