Debug monitor
● Debug monitor for the S1C33 Family
● Runs on the target board providing a low-cost
debug environment
● Controlled with the debugger in a PC through
the S5U1C330MxD1 I/F board
■ FEATURES
• S5U1C330M2S is the debug monitor program for the S1C33 Family.
• Works on the user board by linking with the user program.
• Approx. 10KB ROM, approx. 2.5KB RAM and 1 ch of SIO are required for S5U1C330M2S operation. No
interrupt resource is used.
• The debug monitor on the target board is controlled by the db33 debugger in the PC connected via the
S5U1C330MxD1 board with the RS232C cable. S5U1C330M1D1 for 5V system and S5U1C330M2D1 for
3.3V system are available. They support 115,200bps data transfer, and are connected to the user board with
12 pins (standard) or 5 pins (minimum).
• S5U1C330M2S supports basic debug functions such as program downloading to RAM and Flash memory,
memory dump, register read/write, stepping, program running, and PC break function.
• The S5U1C330M2S middleware including all source codes is provided with a CD-ROM. Simple I/F method of
S5U1C330M2S allows easy implementation with the user program.
• The debugging environment does not need the ICE. The S5U1C330M2S debugging environment can be
implemented to the final product.
