Compares the data of Sa and Sb when the compare control input "EN" =1 or "EN↑" (
●
1. If the data of Sa is equal to Sb, then set FO0 to 1. If the data of Sa>Sb, then set FO1 to 1. If the data of
Sa<Sb, then set FO2 to 1. If the data of Sa < Sb, then set the FO2 to 1.
Example
Compares the data of 16-bit register

From the above example, we first assume the data of R0 is 1 and R1 is 2, and then compare the data by
●
executing the CMP instruction. The FO0 and FO1 are set to 0 and FO2 (a<b) is set to 1 since a<b.
If you want to have the compound results, such as≧、≦、< > etc., please send =、< and > results to relay first
●
and then combine the result from the relays.
M1919=0, when this command in not executed, FO0, FO1, FO2 will remain in the status at last execution.
●
M1919=1, when this command in not executed, FO0, FO1, FO2 are all cleared to 0.
●
Control M1919 properly to obtain memory-holding function for functional command output.
