debugger for AT89LP214

I'm considering using the Atmel LP214 to act as a translator between 
legacy hardware and a new imager (camera) chip. It's 14pin, has enough 
Flash and RAM, and has the UART and counter to make life easy, but I'm a 
little unclear on how one debugs code on a part like this.

I'm not interested in going back to the compile-burn-run puzzle or 
dropping breadcrumbs (printf-style "begin Main()") - I like to step 
through, set breakpoints and examine memory. Atmel shows how to use a 
serial in circuit programmer connection, but it doesn't say JTAG so my 
question is: Is there a debugger available for the AT89LP214?

TIA,
Bob

 From the data sheet at:
http://www.atmel.com/dyn/products/product_card.asp?part_id=3955

The AT89LP213/214 On-chip Debug (OCD) System uses a two-wire serial 
interface to control
program flow; read, modify, and write the system state; and program the 
nonvolatile memory.


So, yes.

Why not use the ATtiny2313 instead?
2 kB code, SRAM, EEPROM and UART.

You can get a free IAR C compiler (limited to 4 kB) also free gcc compiler.
AVR Studio is free.
STK500 is one of the better dev boards around.
JTAGICE Mk II is supporting the 2313 using debugwire
and will also support a vast number of 8 and 32 bit AVRs.
(There is a low cost AVR Dragon as well)

The AVR simulator inside free studio will help you along if you choose not 
to
get the JTAGICE Mk II.

Thanks, Ulf! I'm already using the JTAGICE Mk II/AVR Studio on the 
ATMegas, I just hadn't noticed the ATtiny parts - my bad.

If you go to
http://www.atmel.com/dyn/products/tools.asp?family_id=604

you will see they have a Simulator, and also an emulator add-on for
Keil systems.

A stand alone OCD from Atmel (that does not need Keil) is 'nearing
release'
it will use a RS232 port on the PC
