9.8.3 SIM Break Flag Control Register
MC68HC708AS48
MOTOROLA
—
Rev. 4.0
Address:
ILAD — Illegal Address Reset Flag
LVI — Low-Voltage Inhibit Reset Flag
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:
In some module registers, this read/write bit will enable software to
clear status bits by accessing status registers only while the MCU is
in a break state. To clear status bits during the break state, the BCFE
bit must be set.This operation is important for modules with status bits
which can be cleared only by being read. See the register
descriptions in each module for additional details.
1 = Illegal address reset since last read of RSR
0 = Power-on reset or read of RSR since last illegal address reset
1 = LVI reset since last read of RSR
0 = Power-on reset or read of RSR since last LVI reset
1 = Status bits clearable during break
0 = Status bits not clearable during break
