Table 22
Once NAC and NAC is programmed within the valid range, entry to User Mode is always
possible. If a LIN frame is received within the delay period(NAC = 02
processed as in the BSL mode and User mode will not be entered. Alternatively, user
can erase the NAC values (and/or program an invalid NAC) to enter BSL mode. This can
be done by having a Flash erase(/program) user-routine in the Flash memory.
User Mode Entry 2

•
Once the chip is in BSL mode and Flash memory is protected with LSB of PASSWORD
set to 1, User Mode can be entered with or without delay depending on the NAC values.
The concept of using NAC as delays are similiar to
definition of NAC parameter when flash is protected.
Once NAC is valid and programmed with the valid range, entry to User Mode is always
possible. If a LIN frame is received within the delay period (NAC = 02
specified in
entered. Alternatively, user can erase the NAC value (and/or program an invalid NAC)
to enter BSL mode. This can be done by having a user-routine in Flash to erase the
