Latching of Fuses
Signature Bytes
Calibration Byte
2466T–AVR–07/10
Table 106. Fuse Low Byte
Notes:
The status of the Fuse bits is not affected by Chip Erase. Note that the Fuse bits are locked if
Lock bit1 (LB1) is programmed. Program the Fuse bits before programming the Lock bits.
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 ATmega16 the signature bytes are:
1. $000: $1E (indicates manufactured by Atmel)
2. $001: $94 (indicates 16 Kbytes Flash memory)
3. $002: $03 (indicates ATmega16 device when $001 is $94)
The ATmega16 stores four different calibration values for the internal RC Oscillator. These bytes
resides in the signature row High Byte of the addresses 0x0000, 0x0001, 0x0002, and 0x0003
for 1 MHz, 2 MHz, 4 MHz, and 8 Mhz respectively. During Reset, the 1 MHz value is automati-
cally loaded into the OSCCAL Register. If other frequencies are used, the calibration value has
to be loaded manually, see
