Latching of Fuses
Signal Names
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. The signature bytes are given in
Table 25-6.
The ATmega165P has a byte calibration value for the internal RC Oscillator. This byte resides in
the high byte of address 0x000 in the signature address space. During reset, this byte is auto-
matically written into the OSCCAL Register to ensure correct frequency of the calibrated RC
Oscillator.

This section describes how to parallel program and verify Flash Program memory, EEPROM
Data memory, Memory Lock bits, and Fuse bits in the ATmega165P. Pulses are assumed to be
at least 250 ns unless otherwise noted.
In this section, some pins of the ATmega165P are referenced by signal names describing their
functionality during parallel programming, see
270. Pins not described in the following table are referenced by pin names.
The XA1/XA0 pins determine the action executed when the XTAL1 pin is given a positive pulse.
