Device Overview MC9S12HY/HA-Family

1.3.18 On-Chip Voltage Regulator (VREG)

• Linear voltage regulator with bandgap reference

• Low-voltage detect (LVD) with low-voltage interrupt (LVI)

• Power-on reset (POR) circuit

• Low-voltage reset (LVR)

• High temperature sensor

1.3.19 Background Debug (BDM)

• Non-intrusive memory access commands

• Supports in-circuit programming of on-chip nonvolatile memory

1.3.20 Debugger (DBG)

• Trace buffer with depth of 64 entries

• Three comparators (A, B and C)

— Comparators A compares the full address bus and full 16-bit data bus

— Exact address or address range comparisons

• Two types of comparator matches

— Tagged This matches just before a specific instruction begins execution

— Force This is valid on the first instruction boundary after a match occurs

• Four trace modes

• Four stage state sequencer
