LiteX MMIO registers (referred to as Configuration and Status
|
||
|
|
registers, or CSRs) are spread across adjacent 8- or 32-bit
|
||
|
|
subregisters, located at 32-bit aligned MMIO addresses. Use
|
||
|
|
this to select the appropriate size (1 or 4 bytes) matching
|
||
|
|
your particular LiteX build.
