/**
|
||
|
|
* All AVR targets carry a three-byte signature that is *usually* unique to the target.
|
||
|
|
*
|
||
|
|
* The AVR target signature consists of three bytes: 0xAABBCC
|
||
|
|
* Byte AA (byteZero) identifies the manufacture of the target (usually 1E for Atmel/Microchip)
|
||
|
|
* Byte BB (byteOne) sometimes indicates the flash/ram capacity of the target
|
||
|
|
* Byte CC (byteTwo) identifies the target
|
||
|
|
*
|
||
|
|
* Some AVR targets have been found to carry identical signatures. For example, the AT90PWM1, AT90PWM2B
|
||
|
|
* and the AT90PWM3B all carry a signature of 0x1E9383. Although these devices may not differ in
|
||
|
|
* significant ways, Bloom does still take duplicate signatures into account, to ensure that the correct
|
||
|
|
* part description file is used.
|
||
|
|
*
|
||
|
|
* This class represents an AVR target signature.
