10.3.1.1 Global Registers Overview
The DSCC4 global registers are used to configure and control the DMA controller,
central FIFOs and genral device functions.
The full 32 bit address location of each global register consists of:
• Base Address Register 0 (PCI Configuration Space, address location 10
• Register address offset, which is in the range 0000
All registers are 32-bit organized registers.
Table 43 provides an overview about all global registers:
