It also retrieves register values if requested by the operation.
However, this argument assumes that the register values are changed using conventional set and clear operations which inevitably generate entropy.
There may be some special-purpose register values that differ between the two, but the basic functioning of the processor doesn't change.
After that register has been shifted out, the master and slave have exchanged register values.
Finally it will increase (increment) the register value by the amount specified.
The simplest technique is to scan out the register values into a memory before shutting down a module.
A thread initiates execution on one or more newly allocated threads by setting their initial register values.
Unconditional branches may move execution to a location given by a register value or a PC-relative offset.
Routines typically push the register values to the 6502 stack.
A register value can set the Player or Missile pixels width to 1, 2, or 4 color clocks wide.
