Overview
The TCMP instruction compares the specied time (
hours:minutes:seconds
) with the time of an internal
real-time clock and outputs the comparison result.

Function
The specied time (
hours:minutes:seconds
) is compared with the time of an internal real-time clock. The comparison
result is output.
S1 represents hours, in the range 0 to 23.
S2 represents minutes, in the range 0 to 59.
S3 represents seconds, in the range 0 to 59.
S is the head address of registers that store the current time value of a real-time clock, that is, the data read by the TRD or
MOV instruction.
D is the head address of three consecutive variable units that store the comparison result.
