2.1.2.2 MultiByteInt31-(2 Bytes)

The MultiByteInt31-(2 Bytes) packet is used to store unsigned integers in the range of 0x0080 to 0x3FFF (decimal 128 to 16383) inclusive.

MultiByteInt31 (14 bits encoded in 2 bytes)

0	1	2	3	4	5	6	7	8	9	1 0	1	2	3	4	5	6	7	8	9	2 0	1	2	3	4	5	6	7	8	9	3 0	1
Value_B							Value_A

Value_B (7 bits): Second seven LSB of value

Value_A (7 bits): First seven LSB of value

0	1	2	3	4	5	6	7	8	9	1 0	1	2	3	4	5
0	Value_B							1	Value_A

Example: decimal 145

0	1	2	3	4	5	6	7	8	9	1 0	1	2	3
0	0	0	0	0	0	1	0	0	1	0	0	0	1

Encodes as follows.

0	1	2	3	4	5	6	7	8	9	1 0	1	2	3	4	5
0	0	0	0	0	0	0	1	1	0	0	1	0	0	0	1

Thus, the decimal value 145 is encoded as 2 bytes, as in the following example.

 0x91 0x01

Example: decimal 5521

0	1	2	3	4	5	6	7	8	9	1 0	1	2	3
0	1	0	1	0	1	1	0	0	1	0	0	0	1

Encodes as follows.

0	1	2	3	4	5	6	7	8	9	1 0	1	2	3	4	5
0	0	1	0	1	0	1	1	1	0	0	1	0	0	0	1

Thus, the decimal value 5521 is encoded in 2 bytes, as in the following example.

            
 0x91 0x2B
