This is a suggested modification to the EEPROM documentation. I failed to find a better place to make this suggestion.
The existing eeprom documentation:
file:///Applications/Arduino.app/Contents/Resources/Java/reference/EEPROMRead.html
and the companion EEPROMWrite.html
show parameters like this:
Parameters
address: the location to read from, from 0 to 511 (int)
I understand from elsewhere in the forums that the 511 is not a true limitation, and that the upper limit to this parameter is a function of the installed chip, therefore the 511 should be modified to show that higher addresses are possible and are hardware dependent.
Therefore I suggest the Parameters section be changed to:
Parameters
address: the location to read from (or write to), from 0 to nnn (int), when nnn is at least 511. The maximum value for nnn is dependent on which Arduino board you are running.
