Group Addressing (with Data
Field)
2186A–WIRE–08/02
- WUA: ADD = '0000 0000 0000 0xxx xxx0' (6 bits in bold depending on the device),
ADDL = yyyyy depends on the target devices to be reached: '0 0110' (individual), '0
0011' (whole sub-group), '0 0010' (whole group)
So for all the 15 devices:
WUA = 'y yyyy 0000 0000 0000 0001 0010' number 1/group 1/sub-group 1
WUA = 'y yyyy 0000 0000 0000 0010 0010' number 2
WUA = 'y yyyy 0000 0000 0000 0011 0010' number 3
WUA = 'y yyyy 0000 0000 0000 0001 1010' number 1/group 1 /sub-group 2
WUA = 'y yyyy 0000 0000 0000 0010 1010' number 2
WUA = 'y yyyy 0000 0000 0000 0011 1010' number 3
WUA = 'y yyyy 0000 0000 0000 0100 1010' number 4
WUA = 'y yyyy 0000 0000 0000 0001 0100' number 1/group 2 /sub-group 3
WUA = 'y yyyy 0000 0000 0000 0010 0100' number 2
WUA = 'y yyyy 0000 0000 0000 0011 0100' number 3
WUA = 'y yyyy 0000 0000 0000 0100 0100' number 4
WUA = 'y yyyy 0000 0000 0000 0001 1100' number 1/group 2 /sub-group 4
WUA = 'y yyyy 0000 0000 0000 0010 1100' number 2
WUA = 'y yyyy 0000 0000 0000 0011 1100' number 3
WUA = 'y yyyy 0000 0000 0000 0100 1100' number 4
To carry out a group wake-up, ADDL = '0 0010' and the wake-up message will be:
for group 1: '10 1010 0001'(Header) + '010'(Address)
for group 2: '10 1010 0001'(Header) + '100'(Address)
To carry out an individual wake-up, ADDL = '0 0110' and the wake-up message will be:
for number 1/group 1/subgroup 1: '10 1010 0001'(Header) + '001 0010'(Address)
...
Example: same configuration as before except:
- 10 bits of data
The wake-up message lasts (10 + 7 + 10) bits x 100 µs = 2.7 ms, so WL2 = 6 ms is
correct.
WL1 = 2 ms and WL2 = 3 x WL1 = 6 ms.
- CTRL1: WUEN = '1', PDN = '0'(so bit 26 = '1' and bit 31 = '0')
maximum length of wake-up message = 10 + 7 (Address) + 10 (Data).
