Non-AMBA intra-chip signals are on-chip signals that are not part of the AMBA bus, for example, the interrupt request signals.

Many of these signals are difficult to control and observe. Therefore PrimeCells have integration test logic to make this task easier. These test features are enabled by programming the MPMC Integration Test Control Register (MPMCITCR). The intra-chip input signal values can then be read using the MPMCITIP1 register. The intra-chip output signals can be controlled using the MPMCITOP register.
