17.2.7 7...prm : Parameter ID

The Parameter ID ﬁeld indicates the parameter type. When transferring parameters (see "Part V Parameter List"

below) individually (as opposed to bulk transfer), this ﬁeld is used to identify the parameter being transferred by

its parameter ID. Any other time, this ﬁeld is ﬁlled with the value 00H.

17.2.8 8...ilen/dlen : index length / data length

This ﬁeld indicates the size of the "11...index" ﬁeld and the "12...data" ﬁeld.

iiB (Binary) = index length

"index length (iiB)" indicates the index ﬁeld length, which is always the following, regardless of the "act" (Action)

value.

iiB......index byte size - 1

dddddB (Binary) = data length

"data length (dddddB)" indicates the size of each data unit (parameter) in the "data" ﬁeld.

The data length differs according to Message Type, as shown below.

17.2.9 9....ps : Parameter Set Number

This ﬁeld is a 2-byte (LSB, MSB) value indicating the number of the parameter set (00mmmmmmmnnnnnnnB

(Binary)) being transferred.

Format: 0pppppppB

Format: 0iidddddB

"act" Value Message Type iiB

00, 01 IPC, IPR index byte size - 1

(Example: When 4 bytes = 3

02, 04 BDS, HDS 2 = 10B

(Packet Number = 3 bytes)

03, 05 BDR, HDR 0 = 00B

(This field is empty, but its length is indicated as 0.)

07 Control 0 = 00B

(The length of this filed is 1 byte.)

"act" Value Message Type dddddB

00 IPC data bit size - 1

(If 1 bit = 00000B; if 32 bits = 11111B)

02, 04 BDS, HDS data bit size - 1 = 01111B

(Since transfer is in 16-bit data, this data length

is always used.)

01, 03, 05, 07 IPR, BDR, HDR or Control 0

Format: 0nnnnnnnB (LSB) 0mmmmmmmB (MSB)
