Explanation of function and operation
1. 16-bit operation (TSUB)
The time data (hour, minute, and second) stored in
,
+1, and
+2 is subtracted from the time data
(hour, minute, and second) stored in
,
+1, and
+2, and the subtraction result (hour, minute, and
second) is stored in
,
+1, and
+2.
When the operation result is smaller than 0 hour, the borrow flag turns ON, and the value simply acquired by
subtraction added by 24 hours is stored as the operation result.
When the operation result becomes "0" (0:0:0), the zero flag turns ON.
subtraction added by 24 hours is stored as the operation result.
When the operation result becomes "0" (0:0:0), the zero flag turns ON.
