While the core is in NMI-mode (after an NMI-request has been accepted and before the
RETI instruction is executed, i.e. the time during a NMI-servicing routine), certain debug
functions are blocked/restricted:
1. No external break is possible while the core is servicing an NMI.
2. A breakpoint into NMI-servicing routine is taken, but single-step is not possible
Hardware breakpoints and software breakpoints proceed as normal while CPU is in NMI-
mode.
Data Sheet
External break requested inside a NMI-servicing routine will be taken only after RETI
is executed.
afterwards.
If a step is requested, the servicing routine will run as coded and monitor mode will
be invoked again only after a RETI is executed.
