Proprietary Radio
23.7.2.1 Command Data Definitions
This section defines data types used in describing the data structures used for communication between
the system CPU and the radio CPU. The data structures are listed with tables. The Byte Index is the offset
from the pointer to that structure. Multibyte fields are little-endian, and halfword or word alignment is
required. For bit numbering, 0 is the LSB. The R/W column is used as follows:
R: The system CPU can read a result back; the radio CPU does not read the field.
W: The system CPU writes a value, the radio CPU reads it and does not modify the value.
R/W: The system CPU writes an initial value, the radio CPU may modify the initial value.
