Technical Data
64
A low-voltage inhibit (LVI) reset is an internal reset caused by a drop in
the power supply voltage to the LVI trip voltage, V
An LVI reset:
An illegal opcode reset is an internal reset caused by an opcode that is
not in the instruction set. An illegal opcode reset sets the ILOP bit in the
SIM reset status register.
If the stop enable bit, STOP, in the mask option register is a logic 0, the
STOP instruction causes an illegal opcode reset.
An illegal address reset is an internal reset caused by opcode fetch from
an unmapped address. An illegal address reset sets the ILAD bit in the
SIM reset status register.
A data fetch from an unmapped address does not generate a reset.
