This command will load an address into the STK500. The next Program Flash, Read 
Flash, Program EEPROM or Read EEPROM command will operate from the address 
set with this command. The command is used in all programming modes. All the 
abovementioned commands will increment an internal address counter, so this 
command needs only to be sent once.

For word-addressed memories (program flash), the Address parameter is the word 
address. 

If bit 31 is set, this indicates that the following read/write operation will be performed 
on a memory that is larger than 64KBytes. This is an indication to STK500 that a load 
extended address must be executed. See datasheet for devices with memories larger 
than 64KBytes.
