10.1.7 Reserved areas in the internal peripheral circuits (C33 STD/Mini core)
When reserved areas in the internal peripheral circuits are displayed using the
S5U1C33001H’s data display function, note that, depending on the type of microcomputer,
the last value read by the C33 core that is held in the bus latch circuit inside the chip may
be displayed.
10.1.8 Operating clock of the S5U1C33001H (C33 STD/Mini core)
When execution of the target program is suspended, the operating clock of S1C33xxx chip
on the target system is forcibly switched to the high-speed clock even if the C33 core may
have been operated with the low-speed clock while the target program was executed. For
this reason, if the high-speed clock is turned off by the target program when the target
system is being operated with the low-speed clock, the S5U1C33001H will be unable to
operate normally after execution of the target program is suspended.
10.1.9 Area 2 of S1C33xxx (C33 STD/Mini/ADV core)
Area 2 of the S1C33xxx (0x0060000 to 0x007FFFF) is reserved as a dedicated area for the
programs that operate the S5U1C33001H. Therefore, no device can be mapped to this area
using a parameter file, and data cannot be written to this area when the target program is
suspended or being executed. If the contents of area 2 are rewritten, the S5U1C33001H
will be unable to operate normally. For details on the parameter file, refer to the
“Debugger” section in the “S5U1C33001C Manual (C Compiler Package for S1C33
Family)”.
10.1.10 Concurrent use of the S5U1C330M2S debug monitor
The S5U1C330M2S cannot be used with the S5U1C33001H simultaneously for debugging
the target program.
The S5U1C33001H can be used for debugging the S5U1C330M2S. In this case, the
S5U1C330M2S must be implemented using “mon33ice.lib” (library supplied with the
S5U1C330M2S package). However, only the following parts in the S5U1C330M2S can be
debugged:
- Part for initial connection to the debugger (gdb.exe)
- Confirming the command functions except for execution commands
- Part for communication to the debugger (gdb.exe)
