What's the difference?

What's the difference between the SX blitz and the SX key?· I know the SX key "provides in-circuit source-level debugging."· What exactly does that mean?· Why doesn't the Blitz do that?

Thanks.

"in-circuit source-level debugging" means just that. "In-circuit" means that the SX can be in the board where it's part of the final product as opposed to having to use the SX on some kind of special development board with jumpers or special circuitry to connect it to the circuitry the SX will be controlling. "Source-level" means just that ... that the debugger (on a PC) displays source information like labels, variables, instructions in assembler format rather than hexadecimal addresses and instructions.

The SX Blitz is simpler and cheaper and doesn't include the hardware necessary to support in-circuit source-level debugging.

The SX Key is more complex and more expensive and allows you to do in-circuit source-level debugging of an SX.

I got the SX Blitz, wish I had the SX Key. There is something about being able to set breakpoints and catching it when start+8 bits serial data has just arrived for example.
