which can then not be used for other

purposes. If in-circuit debugging is not

required, the RESERVED register shown

below may be used for any purpose.

Writing to it will have no effect on the

operation of

CC1010.

Great caution should be used when the

RADR

written.

Since

the

address

consists of two bytes (RADRL and RADRH),

there will be a short interval where the

address is not valid as only one of the

bytes

are written

at a

time.

this

intermediate address point to the very

same location as of the code modifying the

RADR, a malfunction will occur. One

possible work-around is to first write

RADRH to a value pointing to a memory

location not used by the code.
