Data interface, internal cycles
Data interface, merged I-S cycles
Data interface, coprocessor register transfer cycles
During an internal cycle, the ARM9E-S does not require a memory access, as an
internal function is being performed.
The ARM9E-S does not perform merged I-S cycles on the data memory interface.
During a coprocessor register transfer cycle, the ARM9E-S uses the data interface to
transfer data to or from a coprocessor. A memory cycle is not required and the memory
controller does not initiate a transaction.
The coprocessor interface is described in Chapter 6 Coprocessor Interface.
