Signals

1-6
The CPU has four main types of signals:
Memory-interface signals. These signals transfer data among the CPU,
-
memory, and peripherals; indicate program-memory accesses and data-
memory accesses; and differentiate between accesses of different sizes
(16-bit or 32-bit).
Clock and control signals. These provide clocking for the CPU and the
-
emulation logic, and they are used to control and monitor the CPU.
Reset and interrupt signals. These are used for generating a hardware re-
-
set and interrupts, and for monitoring the status of interrupts.
Emulation signals. These signals are used for testing and debugging.
