Flexible Clock Options
• Internal clock source module (ICS) contains
a frequency-locked loop (FLL) controlled by
internal reference
• Helps eliminate the cost of all external
clock components
• Reduces board space
• Increases system reliability
• Precision trimming of internal reference allows typical
0.1% resolution and +0.5% to -1% deviation over
operating temperature and voltage
• Provides one of the most accurate internal clock
sources on the market for the money
• Internal reference can be trimmed from 31.25 kHz to • Allows for trimming to adjust bus clock in
39.065 kHz, allowing for 8 MHz to 10 MHz FLL output
specific applications
Timer
• 8-bit modulo timer with 8-bit prescaler
• Generates periodic trigger for time-based software
loops using timer overflow interrupt
• Allows external timer clock source
• Utilizes TCLK input as event trigger; the timer can
be used as an 8-bit event counter
Analog Comparator
• Option to compare to internal reference
• Requires only a single pin for input signal
• Option to route comparator output directly to pin
• Allows other components in system to see result of
comparator with minimal delay
• Allows operation in MCU STOP mode
• Offers function to wake up the MCU from WAIT/STOP
Real-Time Interrupt
• Real-time interrupt trigger with 3-bit prescaler
• Allows periodic wake-up or software trigger with delay
ranging from 8 ms to 1.024s
• Built-in low power 1 kHz clock source
• Options to use low power 1 kHz internal clock to drive
the RTI
• Minimizes power consumption in MCU STOP
Four Bidirectional Input/Output (I/O) Lines; One Input-Only Line and One Output-Only Line
• Software selectable pull-ups on ports when used as
input (internal pull-up on RESET)
• Eliminates need for external resistors to help reduce
customer system cost
• Software selectable slew rate control on ports when
used on output
• Configures ports for slower slew rate to help minimize
noise emissions from the MCU
• 5-pin keyboard interrupt module with software
selectable polarity on edge or edge/level modes
• Helps to virtually eliminate external glue logic when
interfacing to simple keypads using keyboard scan with
programmable pull-up/pull-down functionality
System Protection
• Watchdog computer operating properly (COP) reset
with option to run from dedicated 1 kHz internal clock
source or bus clock
• Resets device in instance of runaway or corrupted code
• Helps protect in case of clock loss with independent
clock source
• Low-voltage detection with reset or interrupt
• Allows system to write/save important variables before
voltage drops to low
• Holds devices in reset until reliable voltage levels are
reapplied to the part
• Illegal opcode and illegal address detection with reset • Resets device in instance of runaway or corrupted code
• Security feature for flash memory
• Helps prevent unauthorized access to memory to
protect valuable software intellectual property
Background Debugging System
• On-chip BDM
• Provides single-wire debugging and emulation interface
• Eliminates need for expensive emulation tools
• Provides circuit emulation without the need for
additional, expensive development hardware
