E2, IE850A
Table 4-2
Functions Specific to the E2 Emulator
Parameter
Software tracing (LPD
output)
(Refer to section 4.2.)
External trigger
input/output
Note: The output of the combination of a PC value and the corresponding immediate or register value uses one stage of
the internal buffer. When software tracing data have been stored up to the seventh stage of the internal buffer, an
overflow message is stored in the eighth stage.

Not available in GTM debugging.
mode
Selection of a single CPU. (When the debugger is connected to the

emulator, a single target CPU is selected. If the target CPU is changed,
the debugger must be re-connected to the emulator.)
