Notes
• The addresses must be specified within the range of the program memory area available for each
microcomputer model.
An error results if the input one is not a hexadecimal number or a valid symbol.
Error : invalid value (no such symbol / symbol type error)
An error results if the limit is exceeded.
Error : Address out of range, use 0-0xXXXX
• An error results if you attempt to clear an address that has not been set.
Error : Input address does not exist
• For direct input mode, an error results if you attempt to set breakpoints at more than 16 locations at a
time. But for guidance mode, there is no such limitation, so you can specify more than 16 breakpoints
before terminating the command by the [Enter] key.
•You can use this command for multiple times to set new breakpoints.
