Si4010-C2
Description of the XREG register fields on the previous pages includes only the used register bits. The
fields are aligned towards the LSB byte of the XREG register. If the actual XREG register is wider then the
field described the missing bits towards MSB byte are all read as 0's and writing to them has no effect. For
example, the register wPA_CAP contains a single 9 bit field. Since it is more than 8 bits and less then 16 it
occupies two bytes. That's why the prefix letter 'w' denoting a two byte WORD. The bits [15:9] are read as
all zeros and write has no effect. They are aligned towards MSB byte of the wPA_CAP, the one at lower
address since the byte ordering is in big endian fashion.
