Notes: 

1. RetAddr indicates after which of the transmitted bytes on the SPI interface to store the return byte, as the SPI 

interface is implemented as a ring buffer (one byte out, one byte in). 

2.  cmd1, cmd2, cmd3 and cmd4 are the instruction bytes found in the SPI Serial Programming Instruction Set found in 

the device datasheet.

STATUS_CMD_OK 

A status value indicating the result of the 
operation, always OK 

 

See CMD_PROGRAM_FUSE. This command is basically the same as the program 
fuse command, only that ISP commands for programming the lock byte must be 
supplied. 

See CMD_READ_FUSE. This command is basically the same as the read fuse 
command, only that ISP commands for reading the lock byte must be supplied.

See CMD_READ_FUSE. This command is basically the same as the read fuse 
command, only that ISP commands for reading one of the signature bytes must be 
supplied. 

XML path: /AVRPART/ICE_SETTINGS/STK600/IspReadSign/ 

See CMD_READ_FUSE. This command is basically the same as the read fuse 
command, only that ISP commands for reading the OSCCAL byte must be supplied. 

XML path: /AVRPART/ICE_SETTINGS/STK600/IspReadOsccal/ 

This is a generic command that can be used to execute any of the ISP commands. 
The command writes a number of bytes to the SPI bus, and returns a number of 
bytes.
