1.4 Block Diagram
Freescale Semiconductor
* This block diagram shows only one particular module to port routing. Detail module routing for different
applications can be found in Signal Description Section.
* Some pins are not available in 100-pin package.
* IPbus runs at 1/2 frequency of S12 core bus, which is controlled by REFDV register of CRG_U module.
*Qbus refers to the data transfer channels between IQUE and USB/ATA5HC/CFHC/MSHC/SDHC/SMHC.
