3.1 Control Registers
The control registers provide the main interface between
the host controller and the on-chip RF controller logic.
Writing to these registers controls the operation of the
interface, while reading the registers allows the host
controller to monitor operations.
The control register memory is partitioned into the short
address control register section and the long address
control register section.
All reserved registers may be read but their contents
must not be changed. When reading and writing to
registers which contain reserved bits, any rules stated
in the register definition should be observed.
