The shared data RAM is a 4.5K memory-mapped section of
RAM that contains the link control data, RF programming
look-up table, and the link payload. This RAM can be read
and written in the same way as the Static RAM space and
can also be read by the sequencer in the Bluetooth LLC. Ar-
bitration between these devices is performed in hardware.
Table 33 shows the memory map of the Bluetooth LLC
shared Data RAM.
