All the data in this instruction is represented in binary (if there is anegative value it is represented using the 2's complement.)B15 B0 B15 B0S D (sec) -59 sec~59 secSecondS+1D+1 (min) -59 min~59 minB31 B16 D+2 (hr) -32768 hr~32767 hr↑The bit B31 of the secondregister is used as the signbit of the second value.↑The bits B15 of each register are used asthe sign bit of the hour : minute : secondvalue.• As shown in the diagram above, after convert to hour : minute : second value, the minute : second value canonly be in the range of -59 to 59, and the hour number can be in the range of -32768 to 32767 hours.Because of this, the maximum limit of D is -32768 hours, -59 minutes, -59 seconds to 32767 hours, 59minutes, 59 seconds, the corresponding second value of S which is in the range of -117968399 to117964799 seconds. If the S value exceeds this range, this instruction cannot be carried out, and will set theover range flag "OVR" to 1. If S = 0 then result is 0 flag "D = 0" will be set to 1.• The program in the diagram below is an example of this instruction. Please note that the content of theregisters are denoted by hexadecimal, and on the right is its equivalent value in decimal notation.X062P.
