The 350 bytes of XDATA in location 0xFDA2-
0xFEFF on CC2510F32 and CC2511F32 do not
retain data when power modes PM2 or PM3
are entered. Refer to Section 13.1.2 on Page
75 for a detailed description of power modes.
11.2.2 8051 Memory Space
This section describes the details of each
standard 8051 memory space. Any differences
between
the
standard
8051
and
CC2510Fx/CC2511Fx is described.
The 256 bytes from 0xFF00 to 0xFFFF are the
DATA memory space mapped to XDATA.
These bytes are also reached through the
DATA memory space.
11.2.2.1 XDATA Memory Space
On a standard 8051 this memory space would
hold any extra RAM available.
In addition the following is mapped into the
XDATA memory space:
The 8, 16, and 32 KB flash program memory is
mapped into the address ranges 0x0000 -
0x1FFF, 0x0000 - 0x3FFF, and 0x0000 -
0x7FFF respectively.
• Radio registers are mapped into
address range 0xDF00 - 0xDF3D.
• I2S registers are mapped into the

KB SRAM, starting at address 0xF000.
address range 0xDF40 - 0xDF48.
