Special utility relays 2103 to 2111 can be set to turn ON or OFF using LDA and STA
instructions as well as SET and RES instructions. Example below illustrates how
one program can be made shorter using LDA and STA instructions.
• LDA $0268
When LDA $0268 is executed, the following data is input to the internal register.
Internal register
When STA 2100 is executed, the data in the internal register is assigned to 16
special utility relays starting from 2100 to 2115.
Thus, 2103, 2105, 2106, and 2109 are ON.
