1. Lock bits re-programming
2.
Lock bits re-programming
MISO output driver is not disabled by Slave Select (SS) signal
MISO output driver is not disabled by Slave Select (SS) signal
Attempt to re-program Lock bits to present, or lower protection level (tampering attempt),
causes erroneously one, random line of Flash program memory to get erased. The Lock bits
will not get changed, as they should not.
Problem Fix / Workaround
Do not attempt to re-program Lock bits to present, or lower protection level.
When SPI is configured as a slave and the MISO pin is configured as an output the pin out-
put driver is constantly enabled, even when the SS pin is high. If other slave devices are
connected to the same MISO line this behaviour may cause drive contention.
Problem Fix / Workaround
Monitor SS pin by software and use the DDRB2 bit of DDRB to control the MISO pin driver.
