System Integration Module (SIM)
19.8.3 SIM Break Flag Control Register
Technical Data
296
Address:
ILAD — Illegal Address Reset Bit (opcode fetches only)
MODRST — Monitor Mode Entry Module Reset Bit
LVI — Low-Voltage Inhibit Reset Bit
The SIM break control register contains a bit that enables software to
clear status bits while the MCU is in a break state.
BCFE — Break Clear Flag Enable Bit
Reset:
Read:
Write:
This read/write bit enables software to clear status bits by accessing
status registers while the MCU is in a break state. To clear status bits
during the break state, the BCFE bit must be set.

1 = Last reset caused by an opcode fetch from an illegal address
0 = POR or read of SRSR
1 = Last reset caused by monitor mode entry when vector locations
0 = POR or read of SRSR
1 = Last reset caused by the LVI circuit
0 = POR or read of SRSR
1 = Status bits clearable during break
0 = Status bits not clearable during break
