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
