(c) Control conditions
• Designation of the multiplicand data address (APSH#XXXX)
Designate the address where the multiplicand data is stored.
• Designation of the multiplier data address (APSH/IPSHD#XXXX)
Designate the address where the multiplier data is stored.
• Designation of the operation result output address (APSH#XXXX)
Designate the address where the result of operation is output.
The address is stored as 4-byte data.
• Designation of the type of operation (IPSH X).
Designate the data length and the data type of multiplicand/multiplier.
1st digit = 0: 1byte
= 1: 2 bytes
= 2: 4bytes
2nd digit = 0: Constant data
= 1: Address data
• Execution command (ACT)
ACT = 0: The binary-data multiplication instruction is executed.
R1 remains unchanged.
ACT = 1: The binary-data multiplication instruction is not executed.
• Error output (OUT)
OUT = 0: Normal
OUT = 1: Error
• #2999
Operation status is written.
d0 = 1: 0
d1 = 1: Negative
d5 = 1: Overflow
