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.
