ATmega163(L)
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 (output). After RESET is set low, the Programming Enable instruction
needs to be executed first before program/erase operations can be executed.
Figure 86. Serial Programming and Verify
Notes:
When programming the EEPROM, an auto-erase cycle is built into the self-timed pro-
gramming operation (in the Serial mode ONLY) and there is no need to first execute the
Chip Erase instruction. The Chip Erase operation turns the content of every memory
location in both the Program and EEPROM arrays into $FF.
The Program and EEPROM memory arrays have separate address spaces:
$0000 to $1FFF for Program memory and $0000 to $01FF for EEPROM memory.
The device can be clocked by any clock option during Serial Programming. The mini-
mum low and high periods for the serial clock (SCK) input are defined as follows:
Low: > 2 MCU clock cycles
High: > 2 MCU clock cycles
