||2.0 Beta 1|
A register stores a single multi-bit value, which is displayed in
hexadecimal within its rectangle, and is emitted on its
Q output. When the clock input
(indicated by a triangle on the south edge) indicates so,
the value stored in the register changes to the value of the
D input at that instant. Exactly when the clock input indicates
for this to happen is configured via the Trigger attribute.
The reset input resets the register's value to 0 (all
zeroes) asynchronously; that is, as long as reset
is 1, the value is pinned to 0, regardless of the clock input.
- East edge, labeled Q (output, bit width matches Data Bit Width attribute)
- Outputs the value currently stored by the register.
- West edge, labeled D (input, bit width matches Data Bit Width attribute)
- Data input: At the instant that the clock value rises from 0 to 1,
the register's value changes to the value of the D input at
- West edge, labeled en (input, bit width 1)
- Enable: When this is 0, clock triggers are ignored. The current bit
continues to appear on the output. The clock triggers are enabled when this
input is 1 or undefined.
- South 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 value
of the D input.
- South edge, labeled 0 (input, bit width 1)
- Asynchronous reset: When 0 or undefined, this input has no effect.
As long as it is 1, the register's value is pinned to 0. This occurs
asynchronously - that is, without regard to the current clock input
value. As long as this is 1, the other inputs have no effect.
- Data Bits
- The bit width of the value stored in the register.
- Configures how the clock input is interpreted. The value
indicates that the register should update its value at the instant when the
clock rises from 0 to 1. The
falling edge value indicates that it should
update at the instant the clock falls from 1 to 0. The
high level value
indicates that the register should update continuously whenever the clock
input is 1. And the
low level value indicates that it should update
continuously when the clock input is 0.
- The text within the label associated with the clock component.
- Label Font
- The font with which to render the label.
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.
Text Tool Behavior
Allows the label associated with the component to be edited.
