Read Microprocessor IC Freescale MC9S08QD4 which has been protected and the content inside the memory has been locked:
8-Bit HCS08 Central Processor Unit (CPU)
HC08 instruction set with added BGND instruction
Background debugging system
Breakpoint capability to allow single breakpoint setting during in-circuit debugging (plus two more breakpoints in on-chip debug module)
ADC — 4-channel, 10-bit analog-to-digital converter with automatic compare function, asynchronous clock source,
temperature sensor and internal bandgap reference channel. ADC is hardware
triggerable using the RTI counter.
TIM1 — 2-channel timer/pulse-width modulator; each channel can be used for input capture, output compare, buffered edge-aligned PWM, or buffered center-aligned PWM
Flash read/program/erase over full operating voltage and temperature
Flash size:
— MC9S08QD4/S9S08QD4: 4096 bytes
— MC9S08QD2/S9S08QD2: 2048 bytes RAM size
TIM2 — 1-channel timer/pulse-width modulator; each channel can be used for input capture, output compare, buffered
edge-aligned PWM, or buffered center-aligned PWM
KBI — 4-pin keyboard interrupt module with software selectable polarity on edge or Read Microprocessor IC Freescale MC9S08QD4
— MC9S08QD4/S9S08QD4: 256 bytes
— MC9S08QD2/S9S08QD2: 128 bytes edge/level modes
Input/Output
· Wait plus three stops
Clock Source Options
Four General-purpose input/output (I/O) pins, one input-only pin and one output-only pin. Outputs 10 mA each, 60 mA maximum for package.
ICS — Internal clock source module (ICS) containing a frequency-locked-loop (FLL) controlled by internal. Precision trimming of internal reference allows 0.2% resolution and 2% deviation over temperature and voltage.
Software selectable pullups on ports when used as input
Software selectable slew rate control and drive strength on ports when used as output
Internal pullup on RESET and IRQ pin to reduce customer system cost
System Protection
Watchdog computer operating properly
(COP) reset with option to run from dedicated 32 kHz internal clock source by
· Single-wire background debug interface
Low-voltage detection with reset or interrupt
Illegal opcode detection with reset
Illegal address detection with reset
