(4) The following will happen when an underflow or overflow is generated in an operation result:
The carry flag in this case does not go ON.
BK-
(1) Subtracts n points of BIN data from the device designated by and n-points of BIN data
from the device designated by and stores the result from the device designated by
onward.
(2) Block subtraction is performed in 16-bit units.
(3) The constant designated by can be between 32768 and 32767 (BIN 16-bit data).
(4) The following will happen when an underflow or overflow is generated in an operation result:
The carry flag in this case does not go ON.
Operation Error
(1) In any of the following cases, an operation error occurs, the error flag (SM0) turns ON, and
an error code is stored into SD0.
• The n-bit range from the , or device exceeds the range of that device.
(Error code: 4101)
• The device ranges of and overlap. (Except when the same device is assigned to
and ) (Error code: 4101)
• The device ranges of and overlap. (Except when the same device is assigned to
