Hi, i have a question about an access restriction of writing to on-chip flash after setting the security bit. Can i program the flash through an EFC after setting the security bit?
Hi, i have a question about an access restriction of writing to on-chip flash after setting the security bit.
Setting the security bit disables any access to the flash through external interfaces (ICE/FFP/...). The type of access (read or write) is not relevant.
Internal access to the flash is not affected.
One more question, can I use JTAG interface after setting the security bit? If so, I can read on-chip flash using an EFC, can't I?
if you set the security bit, you can erase the internal flash using JTAG but not read it.
