Abstract
PURPOSE: To realize various types of complicated control actions through the simple circuit just by altering the contents of ROM.
CONSTITUTION: First full "0" is set to register 3 as the initial stage. Now if the signal is supplied to terminal 7 at the first clock, ROM2 gives its contents 0001 to ROM1 and register 3. As a result, ROM1 delivers the control signal only to terminal 05. At the second clock, the address of ROM1 is decided by output 0001 of register 1 plus the signals applied to terminals 5 and 6. In this case, ROM2 delivers 0010 to ROM1 and register 3 with supply of "0" and "1" to terminals 5 and 6. Then ROM1 delivers the control signal to terminal 01. In such way, the address signal of ROM1 is produced by ROM2, and thus ROM1 delivers the control signal corresponding to the address signal.
