Slow AMBA Peripherals
13.1 Introduction
This chapter describes the peripherals that are connected to the 3.68MHz internal peripheral
bus; these are peripherals that need relatively low data rates on the internal bus. These
peripherals are not supported by the on-chip DMA controller (but can be supported by 'virtual
DMA'—that is, software).
Further details on the internal bus are included in Chapter 3, Architecture Overview.
