FUSEBYTE5 - Non-Volatile Memory Fuse Byte 5
Table 4-4.
• Bit 0 - Reserved
This fuse bit is reserved. For compatibility with future devices, always write this bit to one when
this register is written.
• Bit 7:6 - Reserved
These fuse bits are reserved. For compatibility with future devices, always write these bits to one
when this register is written.
• Bit 5:4 - BODACT[1:0]: BOD operation in active mode
The BODACT fuse bits set the BOD operation mode when the device is in active and idle mode
of operation.
For details on the BOD and BOD operation modes refer to
Table 4-5.
• Bit 3 - EESAVE: EEPROM memory is preserved through the Chip Erase
A chip erase command will normally erase the Flash, EEPROM and internal SRAM. If the
EESAVE fuse is programmed, the EEPROM is not erased during chip erase. In case EEPROM
is used to store data independent of software revision, the EEPROM can be preserved through
chip erase.
