Great caution should be used when the
RADR is written. As the address consist 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. If 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.
RESERVED (0xE7) - Reserved register, used by Chipcon debugger software
Bit Name
R/W Description
7:0 RESERVED(7:0) R/W Reserve register, which is used by Chipcon debugger software.
RESERVED may be used for other purposes if Chipcons
debugger software is not needed.
RDATA (0xB9) - Replacement Data
Bit Name
R/W Description
7:0 RDATA(7:0) R/W Replacement data.
Used to replace the byte at program memory address RADR with
the data from RDATA, if RADR > 0.
RADRH (0xBB) - Replacement address, high byte
Bit Name
R/W Description
7:0 RADR(15:8) R/W Replacement address, high byte.
Used to replace the byte at program memory address RADR with
the data from RDATA, if RADR > 0.
RADRL (0xBA) - Replacement address, low byte
Bit Name
7:0 RADR(7:0)
R/W Description
R/W Replacement address, low byte.
Used to replace the byte at program memory address RADR with
the data from RDATA, if RADR > 0
Chip Version / Revision
CC1010 has a SFR register CHVER which
can be read to decide the chip type and
current revision. The register description is
shown below.
CHVER (0x9F) - Chip Version / Revision Register
Bit Name
7:2 CHIP_TYPE
1:0 CHIP_REV
R/W Description
R
CHIP_TYPE is a read only status word, which gives the type
number of the chip.
000000 : CC1010
000001 - 111111 : Reserved for future use
R
CHIP_REV is a read only status word, which gives the chip
revision number of the chip. Current chip revision is 01
