Table 2-1.
ATmega48A/48PA/88A/88PA/168A/168PA/328/328P support a real Read-While-Write Self-Pro-
gramming mechanism. There is a separate Boot Loader Section, and the SPM instruction can
only execute from there. In ATmega 48A/48PA there is no Read-While-Write support and no
separate Boot Loader Section. The SPM instruction can execute from the entire Flash.
A comprehensive set of development tools, application notes and datasheets are available for
download on http://www.atmel.com/avr.
Note:
Reliability Qualification results show that the projected data retention failure rate is much less
than 1 PPM over 20 years at 85°C or 100 years at 25°C.
This documentation contains simple code examples that briefly show how to use various parts of
the device. These code examples assume that the part specific header file is included before
compilation. Be aware that not all C compiler vendors include bit definitions in the header files
and interrupt handling in C is compiler dependent. Please confirm with the C compiler documen-
tation for more details.
For I/O Registers located in extended I/O map, “IN”, “OUT”, “SBIS”, “SBIC”, “CBI”, and “SBI”
instructions must be replaced with instructions that allow access to extended I/O. Typically
“LDS” and “STS” combined with “SBRS”, “SBRC”, “SBR”, and “CBR”.
