(0014) * Description   : This Program allows an AVR with bootloader capabilities to 
(0015) *                 Read/write its own Flash/EEprom. To enter Programming mode   
(0016) *                 PD2 is checked, it this pin is pulled low, programming mode  
(0017) *                 is entered. If not, normal execution is done from $0000 
(0018) *                 "reset" vector in Application area.
(0019) *                 The PD2 pin should be pulled HIGH by an external Pull-up 
(0020) *                 resistor.
(0021) *
(0022) * Other info    : Code must be modified to use this specific code with devices
(0023) *                 other than ATmega161. Following change should be made:
(0024) *                    -Specify device in define list (e.g. _ATMEGA163)
(0025) *                 
(0026) *                 When using this code with (future) parts other than ATmega32,
(0027) *                 ATmega161 and ATmega163, it will be necessary to change more 
(0028) *                 than the device name. The changes that should be made is:
(0029) *                    -Device name
(0030) *                    -Device signature and memory settings (defines.h)
(0031) *                    -Device code
(0032) *                    -Linker file
(0033) *
(0034) *                 In general the linker file should always be verifyed to match
(0035) *                 the used part's boot address and size. Note that memory size
(0036) *                 is specified in bytes in the linker file.
