4.1.4 Individual Parameter Operations
This section describes parameter operation formats.
IPR Communication Flow
A session consists of an IPC being sent in reply to an IPR request, or an IPC being sent and the session being terminated with without a request.

tt | 0100aaaa | aaaa = IPC/IPR |
d0[0] | 00100000 | Parameter Modify Message ID = 20H |
d0[1] | 0000cccc | cccc = Cat (Parameter Set Category) |
d0[2] | 0ttttttt | 0TTTTTTT0ttttttt = Type ID |
d0[3] | 0TTTTTTT |
|
d0[4] | 0mmmmmmm | 0MMMMMMM0mmmmmmm = Mdev ID |

d0[10] | 0ppppppp | qqPPPPPPPppppppp = Parameter ID |
d0[11] | 0PPPPPPP |
|
d0[12] | 0rbbbbqq bbbb = number of parameter block - 1 | |
One less than the number nested parameter block levels in the parameter configuration
bbbb==0 is interpreted as
This means that at least one parameter must be associated with a parameter block.
r = array flag 0...single data 1...array data
Flag indicating whether the data immediately following it is single data or array data
✩Parameter block number specification (number of bytes required for parameter blocks)
d1[0] 0iiiiiii 0iiiiiii =
:
d1[bbbb] 0IIIIIII 0IIIIIII =
Data indicating the block number of the parameter when parameters are nested in a parameter set
✩Section indicating the number of data in a data array and the number of data array numbers (This data string is not necessary in the case of
d2[0] 0ooooooo
d2[1] 0ppppppp oooooooppppppp = top index number of array to send (Number of array where transfer starts)
d2[2] 0qqqqqqq qqqqqqq = number of array members to send (Number of send members in current packet)
In the case of an array that does not fit inside one packet, multiple packets are sent for the length specified by the top index number.
✩One data size (number of bits) minus 1
d3[0] 000zzzzz
zzzzz = number of bits - 1
When zzzz + 1 is: The number of data bytes is: 1 to 7 1
8 to 14 2
15 to 21 3
22 to 28 4
29 to 32 5
✩Following is actual data transfer format, which is added only in the case of IPC
Single Data
When the data size is 29 bits to 32 bits
d4[0] 0xxxxxxx yyyyXXXXXXX....xxxxxxx = Data
:
d4[3] 0XXXXXXX d4[4] 0000yyyy
When the data size is 22 bits to 28 bits
d4[0] 0xxxxxxx yyyyyyyXXXXXXX....xxxxxxx = Data
:
d4[2] 0XXXXXXX d4[3] 0yyyyyyy
When the data size is 15 bits to 21 bits
d4[0] 0xxxxxxx yyyyyyyXXXXXXXxxxxxxx = Data d4[1] 0XXXXXXX
d4[2] 0yyyyyyy
When the data size is 8 bits to 14 bits
d4[0] 0xxxxxxx XXXXXXXxxxxxxx = Data d4[1] 0XXXXXXX
When the data size is 7 bits or less d4[0] 0xxxxxxx xxxxxxx = Data
Array Data
When an entire array is transferred, the format is the same as that for single data.
d4[0][0] 0xxxxxxx yyyyyyy....xxxxxxx = Data
:
d4[0][X] 0yyyyyyy
d4[1][0] 0xxxxxxx yyyyyyy....xxxxxxx = Data
:
d4[1][X] 0yyyyyyy
:
:
d4[N][0] 0xxxxxxx yyyyyyy....xxxxxxx = Data
:
d4[N][X] 0yyyyyyy
Notes: N = oooooooppppppp - 1
X = depends on data size - 1
When zzzz + 1 is: The number of data bytes is: 1 to 7 0
8 to 14 1
14 to 21 2
22 to 28 3
29 to 32 4
