Latching of Fuses
Signature Bytes
Calibration Byte
2467M–AVR–11/04
The Fuse values are latched when the device enters Programming mode and changes
of the fuse values will have no effect until the part leaves Programming mode. This does
not apply to the EESAVE fuse which will take effect once it is programmed. The fuses
are also latched on power-up in normal mode.
All Atmel microcontrollers have a three-byte signature code which identifies the device.
This code can be read in both serial and parallel mode, also when the device is locked.
The three bytes reside in a separate address space.
For the ATmega128 the signature bytes are:
1. $000: $1E (indicates manufactured by Atmel)
2. $001: $97 (indicates 128KB Flash memory)
3. $002: $02 (indicates ATmega128 device when $001 is $97)
The ATmega128 stores four different calibration values for the internal RC Oscillator.
These bytes resides in the signature row high byte of the addresses 0x000, 0x0001,
0x0002, and 0x0003 for 1, 2, 4, and 8 MHz respectively. During Reset, the 1 MHz value
is automatically loaded into the OSCCAL Register. If other frequencies are used, the
calibration value has to be loaded manually, see “Oscillator Calibration Register – OSC-
CAL” on page 39 for details.
