BurnFuse
Burns one of the 88 user accessible fuse bits.
The values in fuses #88-127 are reserved for Fuse MfrID and Fuse SN and cannot be blown via this command. All addresses
above 0x57 (87) will result in an error.
Fuses, with the exception of those initialized by Atmel, have a value of one on shipment from the Atmel factory and transition
to a zero when they are burned.
Fuse bits zero through seven of the fuse array are word lock bits. Burning one of these has the effect of locking the
corresponding 16-bit word within Fuse. Bit 0 locks fuses 0-15, bit 1 locks fuses 16-31 and so on. If bit 0 is burned, then the
value of the lock bits can no longer be changed. The values of lock bits six and seven are ignored by the chip.
The power supply pin must meet the V BURN specification during the entire BurnFuse command in order to burn fuses reliably. If
Vcc is greater than or equal to 3.7 V, then the BurnTime parameter should be set to 0x00 and the internal burn time will be
250 μ s. If Vcc is less than 3.7 V but greater than V BURN then the BurnTime parameter should be set to 0xFFFF and the internal
burn time will be up to 262ms. The chip does not internally check the supply voltage level.
There is a very small interval during t EXEC_BURN when the fuse element is actually being burned. During this interval, the power
supply must not be removed and the watchdog timer must not be allowed to expire or the fuse may end up in a state where it
reads as un-burned but cannot be burned.
