...the world's most energy friendly microcontrollers
A Cortex-M3 lockup gives immediate indication of seriously errant kernel software. This is the result of
the core being locked up due to an unrecoverable exception following the activation of the processor’s
built in system state protection hardware. For more information about the Cortex-M3 lockup conditions
see the ARMv7-M Architecture Reference Manual. The Lockup reset does not reset the Debug Interface.
Set the LOCKUPRDIS bit in the RMU_CTRL register in order to disable this reset source.
9.3.7 System Reset Request
Software may initiate a reset (e.g. if it finds itself in a non-recoverable state). By asserting the
SYSRESETREQ in the Application Interrupt and Reset Control Register (write 0x05FA 0004), a reset is
issued. The SYSRESETREQ does not reset the Debug Interface.
