13.0 REGISTER MAP
Registers are 32 bits (quadlet) wide and all accesses are always done on a quadlet basis. This means that it is not possible to write just the
lower 8 bits, and leave the other bits unaffected (see Section 12.3.2 for more information). The values written to undefined fields/bits are ignored
and thus DON’T CARE.
A full bitmap of all registers is listed in Table 8. The meaning of shading and bit cell values is as follows:
A bit/field with no name written in it and dark shading is reserved and not used.
A bit/field with a name in it and light shading is a READ ONLY (status) bit/field.
A one bit value (0 or 1) written at the bottom of a writeable (control) bit is the default value after power-on-reset.
