2.13 SUBTRACT TIME Instruction (TMSUB)
[Outline]
The TMSUB instruction subtracts one time (hours/minutes/seconds) from another time. The Source is
subtracted from the Dest and the result is stored in the Dest. The formats of Source and Dest are as
follows.
Data Format
Register Offset Data Contents Data Range (BCD)
0 Hours/minutes Upper byte (hours) : 0 to 23
Lower byte (minutes) : 0 to 59
1 Seconds 0000～0059
If the contents of the Dest and Source are with the appropriate ranges, the operation will be performed
normally. After the operation is completed, the [Status] is turned OFF. If the contents of the Dest and
Source are outside the data ranges, the operation is not performed. In this case, 9999H is stored in the
column "second" of the Dest, and the [Status] is turned ON.
