4. Some watchdog timers can only be disabled is a pin is driven high before the target is powered. The table
below lists which tools can support this scenario.
Censorship Unlock
TRACE32 supports censorship unlock via JTAG commands, if the processor supports those commands.
The unlock is supported by all processors but MPC55XX.
In order to unlock the processor when starting the debug session, provide the censorship password to the
debugger using the command
. Size and format of the password depends on
the processor in use.
Censorship unlock on MPC56XX and SPC56X processors
MPC56XX/SPC56X processors only support unlocking during
. Attaching to a censored
processor without resetting it is not possible.
Censorship unlock on MPC57XX, SPC57X/SPC58X and S32R processors
On MPC57XX, SPC57X, SPC58X and S32R processors, the censorship unlock is possible without
asserting reset and also if functional reset is asserted. For the unlock during SYStem.Up, the ability to
successfully unlock the processor depends on which reset pin is connected to the debugger’s reset output.
If the debugger’s reset output is connected to ESR0, SYStem.Up will perform a functional reset and the
unlock will succeed. If the debugger’s reset output is connected to PORST, the processor will perform a
destructive reset and the unlock during SYStem.Up will fail.
