211 / 273 page  211 8042A–AVR–07/09 ATmega16HVB/32HVB 30.4 Calibration Bytes 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 ”Reading the Signature Row from Software” on page 199 for details. 30.5 Page Size 30.6 Serial Programming 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 Table 30-10 on page 212, the pin mapping for SPI programming is listed. Not all parts use the SPI pins dedicated for the internal SPI interface. Table 30-6.
