Modules |
| | Memory map bit(fields) |
| | List of all bit(field) definitions of memory mapped items.
|
| | Memory mapped arrays |
| | These are some macros for easier access of various memory sections. They're all arrays or matrices, using the types that would be the most natural for that concept.
|
| | IO Registers |
| | IO Alternates |
| | Alternate names for some of the registers.
|
