AHB-to-APBX Bridge with DMA (APBX-Bridge-DMA)
7.1 AHB-to-APBX Bridge Overview
The AHB-to-APBX bridge provides the device with an inexpensive peripheral attachment
bus running on the AHB's XCLK. (The X in APBX denotes that the APBX runs on a
crystal-derived clock, as compared to APBH, which is synchronous to HCLK.)
As shown in the following figure, the AHB-to-APBX bridge includes the AHB-to-APB
PIO bridge for a memory-mapped I/O to the APB devices, as well a central DMA facility
for devices on this bus. Each one of the APB peripherals is documented in their own chapters
elsewhere in this document.
