Before issuing any AVR8 JTAG commands the following parameters must be set 
correctly with the CMD_SET_PARAMETER command: 

 

• PARAM_JTAG_ALLOW_FULL_PAGE_STREAM 
• PARAM_JTAG_EEPROM_PAGE_SIZE 
• PARAM2_JTAG_FLASH_PAGE_SIZE 
• PARAM2_JTAG_FLASH_SIZE_H 
• PARAM2_JTAG_FLASH_SIZE_L 
• PARAM_JTAG_DAISY_BITS_BEFORE 
• PARAM_JTAG_DAISY_BITS_AFTER 
• PARAM_JTAG_DAISY_UNITS_BEFORE 
• PARAM_JTAG_DAISY_UNITS_AFTER 

The following memory modes are defined for CMND_WRITE_MEMORY and 
CMND_READ_MEMORY. (The values are the same as for jtagice mkII) 

Table 7-3. Valid Result Values for the answer to this command.
