CHAPTER 8: DEBUGGER
188 EPSON S5U1C63000A MANUAL
(S1C63 FAMILY ASSEMBLER PACKAGE)
Notes
• For the first time this command is executed, no item can be skipped because no default value is set.
• In guidance mode, the following keyboard inputs have special meaning:
"q↵"… Command is terminated. (finish inputting and start execution)
"^↵"… Return to previous item.
"↵"… Input is skipped. (keep current value)
When the command is terminated in the middle of guidance by "q↵", the contents that have been
input up to that time will be modified. However, these contents will not be modified if some cleared
settings are left intact.
• The addresses must be specified within the range of the data memory area available for each micro-
computer 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 0-0xFFFF
• An error results if the start address in the address range is larger than the end address.
Error : end address < start address
• Address and R/W specifications are effective even for 16-bit access (push/pop to and from SP1 stack).
However, the data specification will not have any effect because data is compared with a 4-bit bus. In
this case, specify data with "∗∗∗∗". When setting a break for 4-bit access, be careful not to specify an
address that overlaps the 16-bit access area, because such specification can cause the system to operate
erratically.
• The data value can be input as a binary number with or without mask bits in the range of 4 bits (0 to
0xf). An error results if the limit is exceeded.
Error : invalid data pattern
• An error results if you input the R/W option other than "r", "w" or "∗".
Error : Incorrect r/w option, use r/w/*
• The program stops one to two instructions after the break condition has been met.
