Adding clock data
TADD(P)
These instructions add the time data stored in the device number specified by (s2) and later to the clock data stored in the
device number specified by (s1) and later, and store the result to the device number specified by (d) and later.

Processing details
• These instructions add the time data stored in the device numbers starting from (s2) to the clock data stored in the device
numbers starting from (s1), and store the result to the device numbers starting from (d).
Ex.
When adding 7:48:10 to 6:32:40
• If the sum of two values exceeds 24:00:00, the carry flag turns on, and the result will be the sum minus 24:00:00. For
example, if a time value of 20:20:20 is added to another time value of 14:30:30, the sum is 34:40:50. However, the actual
addition result will be 10:40:50.
• If the result is 0 (0:00:00), the zero flag turns on.
• If 1 second is added to 23:59:59, the result will be 0:00:00. This turns on both the carry flag and the zero flag.
• The table below shows the related devices.
