Serial Programming
The ATmega16HVB/32HVB 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.
Table 30-6.
Table 30-7.
Table 30-8.
Table 30-9.
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.
