Logisim 1.0 8-Bit Register
This component exists only for backwards compatibility with Logisim 1.0X; for new circuits, the Memory library's register is recommended instead.
The register stores a single 8-bit value, which is displayed in hexadecimal within its rectangle, and is emitted via its outputs on its east edge. (Logisim 1.0X did not support multi-bit values, so the register had to have a pin for each individual bit.) At the instant when the clock input (indicated by a triangle on the west edge) rises from 0 to 1, the value stored in the register changes to the value specified through the eight other bits on the west edge.
Poke Tool Behavior
Clicking the register brings keyboard focus to the register (indicated by a red rectangle), and typing hexadecimal digits will change the value stored in the register.
