UINT32

1

[0 … 39]

ByteOffset

Relative address offset [0..39] in output structure.

E.G.: To write “nControl1” the ByteOffset must be 8.

 

UINT32

1

[0x00000000… 0xFFFFFFFF]

BitSelectMask (BSM)

The mask defines write enabled bits in a DWORD. Zero bits are protected and remain unaffected.

 

UINT32

1

[0x00000000… 0xFFFFFFFF]

Value

Only those bits in value are overwritten where BSM equals 1.
