1. GLOSSARY
S5U1C33001H1400 (ICD33V6.0)
ICD mode
Flash programmer mode
This mode is used to debug the target system. Debugging
requires both a PC and the debugger (gdb. exe included in
the S5U1C33001C: C Compiler Package for S1C33
Family).
This mode is used to write programs to the target
system without a PC. Before writing a program to the
target system, you must load the program to the
S5U1C33001H1400 (ICD33V6.0) in ICD mode.
Debugger, gdb.exe (included in the S5U1C33001C: C Compiler Package for S1C33 Family)
Simulator (SIM) mode
ICD6 mode
This mode simulates the execution of the target program on
a PC memory. This mode does not require any other tool.
However, this mode cannot execute ICD-dependent
functions.
This mode performs debugging using the
S5U1C33001H1400 (ICD33V6.0) or ICD board. The
program is executed on the target board. To debug
these products, use this debugger in ICD6 mode.
Target (S1C33xxx)
Normal mode
Debug mode
Ordinary mode in which the target system executes a user
program.
The mode changes to debug mode under the following
conditions:
•
When the break condition set by the debugger (gdb.exe)
is met
•
When the user presses the Break button on the gdb
screen while the debugger (gdb.exe) is connected
•
When a Low level is input to the target system DSIO pin
•
When the CPU executes a brk command
In this mode, the target system accepts control by the
debugger (gdb.exe).
This mode permits various debugging operations,
including display and rewriting of data in registers and
memory.
This mode is activated when the S5U1C33001H1400
(ICD33V6.0) is connected and the power-on sequence
is executed.
