existing NAC values and program an invalid NAC located in address(0FF8
protection mode 0(MSB of PASSWORD is 0) is selected. When Flash protetcion mode
1(MSB of PASSWORD = 1) is selected, the only way to enter BSL mode is to send a LIN
frame within the delay period.
Note: Entering of BSL Mode is not possible if MSB of PASSWORD is 1 and NAC is 01
User Mode Entry 3

•
Once the chip is in BSL mode and Flash memory is protected with LSB of PASSWORD
set to 0, User Mode will be entered immediately. Entering of BSL Mode is not possible
in this type of User mode entry. Hence, changing of Flash code, XRAM code or flash
protection scheme is not allowed. If there is an intention to upgrade Flash content, a pre-
defined routine in the user code via In-Application Programming can be used. But it is
possible only if flash protection mode 0(MSB of PASSWORD to 0) is selected. This
option can be applied to all the user entry mode to change the flash content.
