11.3.2.1 Read
Reading the Flash is done using Load Program Memory (LPM) instructions or
Load (LD*) instructions with an address according to the memory map.
Reading the EEPROM and Signature Row is done using LD* instructions.
Performing a read operation while a write or erase is in progress will result in a bus
wait, and the instruction will be suspended until the ongoing operation is complete.
