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.
