General Description
• ROM Security Bytes¹ to Aid in Locking Out Access to ROM Array
• Mask Option Selectable Computer Operating Properly (COP)
Watchdog System
• On-Chip Temperature Measurement Diode
• Mask Option Selectable Low-Voltage Inhibit to Reset CPU in Low-
Voltage Conditions
• On-Chip Oscillator with Device Selection of Crystal/Ceramic
Resonator or RC Operation and Mask Option Selectable Shunt
Resistor, Approximately 2 MΩ
• Internal Oscillator for Lower-Power Operation, Approximately
100 kHz (500 kHz Selected as a Mask Option)
• Power-Saving Stop Mode and Wait Mode Instructions (Mask
Option Selectable STOP Conversion to Halt and Separate Mask
Option for Fast 16-Cycle Restart)
• Illegal Address Reset
• Internal Steering Diode and Pullup Device on RESET Pin to V_DD
1.4 Mask Options
These MC68HC05JJ6/MC68HC05JP6 mask options are available:
• Sensitivity on External Interrupt, Edge-Triggered or Edge- and
Level-Triggered
• Analog Options:
– Comparator 1 Output, Internal Only or Internal and PB4 Pin
– Sample and Hold Offset, None of Nominal 100 mV
• Oscillator Startup Delay, 16 or 4064 Cycles of Internal Bus Cycles
• STOP Instruction: Enabled or Disabled (Converted to HALT
Instruction)
1. No security feature is absolutely secure. However, Freescale’s strategy is to make reading or
copying the ROM difficult for unauthorized users.
