23.6.1.1 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. Multi-byte fields are little-endian, and half-word or word alignment is
required. For bit numbering, 0 is the least significant bit. 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.

Bytes Field Name Bits Bit Field Name Type Description
Channel to use
0–39: BLE advertising/data channel number
14 channel W 60–207: Custom frequency; (2300 + channel) MHz
255: Use existing frequency
Others: reserved
If bOverride = 1 or custom frequency is used:
0–6 init W 0: Do not use whitening
Other value: Initialization for 7-bit LFSR whitener
15 whitening
0: Use default whitening for BLE advertising/data
7 bOverride W channels
1: Override whitening initialization with value of init
16–19 pParams W Pointer to command specific parameter list
Pointer to command specific result (NULL: Do not store
20–23 pOutput W
results)

This command structure shall be used for all the radio operation commands for BLE support. The first 14 bytes shall be defined
as in Table 23-8.
