Page 11: Autonomous Operation
GREEN LED is on constantly. The right LED of AVR-ISP500-ISO is a bi-color LED which shows the last autonomous operation status for indefinite time. Again, RED is for error, GREEN is for success, off if no status is available due to ongoing operation. - Page 12 AVR-ISP500 STATES SHOW_RESULT if(error) STANDALONE_ISP LED0=on; LED1=off Finished LED0=on else if(empty) LED1=on LED0=blink_fast; LED1=off else LED0=off; LED1=blink_fast Button pressed 5 seconds passed or IDLE button pressed LED0=off LED1=on Button held for 1 second Button pressed Button released SHOW_LOG_STATUS ENABLE_LOGGING if(log_empty) LED0=blink_slow LED0=blink_fast Button held...
- Page 13 Example: LED1 LED0 Error code: 2 flashes – End of error code. LED0 idle idle mem read mismatch lights constantly. CAVEAT: RC calibration in autonomous mode is not supported. The reason is that the programmer has no way to distinguish RC value writes to FLASH from normal data ones.

Page 15: Clock Output
CLOCK OUTPUT: Pin 3 of the ICSP10 connector is normally left unconnected by other ISP programmers. Not ours. In normal programmer state this pin is tri-stated. During programming operation, however, this pin is made output and a square-wave clock is generated. Clock frequency can be adjusted with the AvrStudio Programmer Dialog: After programming operation finishes, this pin is again tri-stated in order not to interfere with the target circuit. -
Page 16: Firmware Upgrade
User is free to use his favorite terminal client (HyperTerminal, minicom, etc) to upload the firmware images taken from our website. The serial port settings for the AVR-ISP500-ISO boot loader are: 9600 baud/sec, 8 data bits, no parity, 1 stop bit. The AVR-ISP500- TINY/MASS/NANO boot loaders implement a USB virtual serial port that is baudrate agnostic. - Page 17 ISP frequency might be too high. Set the ISP frequency to well below ¼ of target MCU clock. Please note that the AVR MCU clock depends on its fuses configuration. Target power might not be stable enough or supply voltage might be ...
