Cyclone PRO User Manual
The first breakpoint set is always a hardware breakpoint, and any
additional breakpoints set are software breakpoints. To make sure
that a hardware breakpoint is being set, make sure only one
breakpoint is being used.
Hardware breakpoints will stop execution in ROM or RAM. Software
breakpoints will stop execution only in RAM.
Experiment with the register interpreter. Use the "View Register
Files..." option in the MultilinkCyclonePRO menu.
Executing an SWI instruction while running is functionally equivalent
to hitting a breakpoint, except that execution stops at the instruction
following the SWI.
A hardware breakpoint may be used to trap a data read/write to
anywhere in the memory map. The debugger stops at the instruction
after the one that accesses the data location.
When the target board is reset by the debugger, power to the
microcontroller may be turned off for a short duration. Although much
of RAM may look the same, some values may have changed.
Class 5
P&E's MON08 Cyclone Device connects to a PC via the serial port. The
Cyclone-to-MCU connection occurs via a standard 16-pin MON08 ribbon
cable. The MON08 Cyclone Device allows the user to auto-detect the
baud rate as well as auto-cycle the power through the MCU system.
Class 7
P&E MON08 Multilink and USB MON08 Multilink cables connect to the
user's MCU system via a standard 16-pin MON08 ribbon cable. MON08
Multilink and USB MON08 Multilink allow one to auto-detect the baud rate
as well as auto-cycle the power through the microprocessor system.
Class 8
P&E's Cyclone Pro communicates with the PC through a Serial, Ethernet
or USB port. The Cyclone Pro can be used to debug and program the
firmware inside of Freescale HC08 microprocessors via a standard 16 pin
