(c) Control conditions
• Designation of the input data address (APSH#XXXX)
Designate the address where the data to be compared is stored.
• Designation of the comparison data address (APSH#XXXX)
Designate the address where the comparison data is stored.
• Designation of the size of the data (LD#XXXX.XX)
LD = 0: 1 byte
LD = 1: 2 bytes
LD = 2: 4 bytes
• Execution command (ACT)
ACT = 0: The binary data comparison instruction is not executed.
ACT = 1: The binary data comparison instruction is executed.
• Result of comparison (APSH#XXXX)
d0 = 1 aaaa = bbbb
d1 = 1 aaaa > bbbb
d2 = 1 aaaa < bbbb
(16)SUBP 034 (Binary Data Search) RR after operation:
Ù
