AVR061
2525B–AVR–04/03
Read Data Memory Read one byte from EEPROM memory.
Command Cmnd_STK_READ_DATA, Sync_CRC_EOP
Command Value 0x71
Response Resp_STK_INSYNC, data, Resp_STK_OK
or
Resp_STK_NOSYNC (If no Sync_CRC_EOP received)
Read Fuse Bits Read Fuse bits. The Fuse bit mapping for the currently supported devices is described
in the appendix.
Note: For ISP Programming, use the Cmnd_STK_UNIVERSAL command with the appropriate
ISP command bytes (found in the device data sheet).
Note that some devices combine Lock bits and Fuse bits in way that actually requires
using the Cmnd_STK_READ_LOCK to retrieve the Fuse byte(s). This is described
closer in the appendix.
Command Cmnd_STK_READ_FUSE, Sync_CRC_EOP
Command Value 0x72
Response Resp_STK_INSYNC, fuse_low, fuse_high, Resp_STK_OK
or
Resp_STK_NOSYNC (If no Sync_CRC_EOP received)
