Logisim 1.0 8-Bit Register

Verhalten
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.
Pins
- East edge, eight pins (outputs, bit width 1 each)
- Outputs the value currently stored by the register, with the lowest-order bit at the northmost pin.
- West edge, eight pins (inputs, bit width 1 each)
- At the instant that the clock value rises from 0 to 1, the register's value changes to the value of the inputs at that instant. The lowest-order bit is at the northmost pin.
- West edge, indicated with a triangle (input, bit width 1)
- Clock input: At the instant that this input value rises from 0 to 1 (the rising edge), the register's value will be updated to the values of the other inputs on the west edge.
Attribute
Keines.
Verhalten des Schaltwerkzeugs
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.
Verhalten des Textwerkzeugs
Keines.
