For example, if a literal (a number) given in the instruction is to be loaded into the working register (W), it is placed on an internal data bus and the W register latch enable lines are activated by the timing and control logic. The internal data bus can be seen in the ...

If the timing interval becomes "large", you need to be aware of how fast the counter might increment so that you can compute the longest interval between reads that guarantees no more than 2^48 increments (so you can unambiguously detect and correct wraparounds). Sometimes you can...
If an interrupt is accepted by the CPU, the microcontroller interrupts a running program and proceeds the program execution at an interrupt source specific vector address where the interrupt service routine is located. After the execution of a RETI (return from interrupt) instruction the program is...

How to check timing conditions Latches, flip-flops, RAMs, and all other sequential subcircuits impose specific timing requirements such as setup and hold times on data, and minimum pulse widths on clock inputs. Should any of these timing conditions get violated, their behavior becomes unpredictable...

The AMD CDNA devices can detect floating point exceptions and can generate interrupts. In particular, they can detect IEEE floating-point exceptions in hardware; these can be recorded for post-execution analysis. The software interrupts shown in the previous figure from the command processor to the...
and forms the basis of the lowest bit of the next micro-instruction address fetched during the succeeding clock cycle. FIG. 64 shows a special forcing driver for the microcode-memory address that forces an opcode of 1 during interrupt recognition. FIG. 65 shows a timing chain used to control...
6. Microcontroller 112 controls the timing and magnitudes of the signals in FIG. 7, in one embodiment. Note that the various signals in FIG. 7 are just one example of voltages applied to memory structure 126 during a memory operation. The timing of the signals in FIG. 7 is one example ...
