List of functions
Specifications that the E2 emulator and IE850A support are listed in the table below. Support for some
debugging-related functions also depends on the debugger. Refer to the user’s manual, etc. for the debugger
you are using.
Table 4-1 Common Functions of the E2 Emulator and IE850A
Parameter
E2 Emulator
IE850A
Connection interface for the flash
programming
2-wire UART or CSI
Connection interface for the debugging
4-pin LPD 5.5 MHz/11 MHz/16.5 MHz/33 MHz
Interface for external tracing
One-lane or four-lane Aurora
tracing
Four-lane Aurora tracing is only
available when the emulation
adapter is in use.
Hot plug-in connection
Available
Multi-core debugging
Mode selection
Asynchronous debugging or synchronous debugging
Initially
stopped
debugging
Programs can be executed in the initially stopped state after a reset.
Break
Software break
In ROM and RAM areas combined: 2000 points
Hardware
break
12 points including those used for both execution and CPU access
conditions (8 points only for execution conditions, and 4 points for
either execution or access conditions)
Comparison with data in access cannot be used as a condition for a
hardware break.
Event break
Available (depends on the debugger)
Forced break
Available
Trace-full
break
Available (during tracing and
software tracing (with LPD
output))
Available (during tracing)
Trace delay
break
Available (during external
tracing)
External trigger
input break
Available
Event
Number of
events that can
be set
Devices that do not include trace functions: 8 points for execution and
8 points for CPU access
Devices that include trace functions or the emulation adapter: 8 points
for execution, 8 points for CPU access, 4 points for DMA access, and 4
points for CRAM access
Note: The availability to specify a range of events for execution
depends on the target device and its version number.
Available
function
Break, performance measurement, trace
Combination of
events
OR, sequential
