(Refer to the System17 Installation Manual—Physical Planning, OrderNo. GA34-0004, for more detailed data on the external synchronization input pulse.)Read ADC0 8 11 16 20 26 31Op code R Fun Zeros Mod DA MA0 0 0 0 1 XXXO 1 0 0 0 0 0 0 0 0 0 0 1 0 0 1 0 0 XXXXXXIII( II II 1 11 III 1 1 1 111 II0 8-F 4 0 0 9 0-3 XThis command stores the binary output value from the ADC into the index register (R),or the accumulator if R=000.
