All Atmel microcontrollers have a three-byte signature code which identifies the device. This
code can be read in both Programming mode, also when the device is locked. The three bytes
reside in a separate address space. The signature bytes of ATmega8HVA/16HVA is given in
Table
Table 27-5.
The ATmega8HVA/16HVA has calibration bytes for the RC Oscillators, internal voltage refer-
ence, internal temperature reference and each differential cell voltage input. These bytes reside
in the signature address space. See
for details.
Both the Flash and EEPROM memory arrays can be programmed using the serial SPI bus while
RESET is pulled to GND. The serial interface consists of pins SCK, MOSI (input) and MISO (out-
put). After RESET is set low, the Programming Enable instruction needs to be executed first
before program/erase operations can be executed. NOTE, in
mapping for SPI programming is listed. Not all parts use the SPI pins dedicated for the internal
SPI interface.
