8.3.3. Master Caching and Buffering Overrides
Some of the peripheral masters connected to the system interconnect do not have the ability to drive the caching and buffering signals of their interfaces. The system manager provides registers so that you can enable cacheable and bufferable transactions for these masters. The system manager drives the caching and buffering signals of the following masters:
Master Peripheral | System Manager Register Group | Register |
---|---|---|
EMAC0 and EMAC1 | emacgrp | l3master |
USB OTG 0 and USB OTG 1 | usbgrp | l3master |
NAND flash | nandgrp | l3master |
SD/MMC | sdmmcgrp | l3master |
At reset time, the system manager drives the cache and buffering signals for these masters low. In other words, the masters listed do not support cacheable or bufferable accesses until you enable them after reset. There is no synchronization between the system manager and the system interconnect, so avoid changing these settings when any of the masters are active.
