Reset Signal Blocking
These commands allow blocking of BL51E reset inputs. The setting is persistent, i.e. it is
stored in non-volatile memory.
In a system with master and slave CPU boards, normally the slave boards will get a reset
whenever the master board resets. With "Reset Signal Blocking" configuration it is
possible to decide at runtime for the slave boards whether they should get a reset
whenever the master board resets or whether the slave board should operate
independently. Additionally with this functionality it is possible to disable external reset
for the master board where needed.
The default mode after factory programming is "Reset enabled".
