7.1.2 LED All Call I
7.1.3 LED Sub Call I
7.1.4 Software Reset I
The last bit of the address byte defines the operation to be performed. When set to logic 1
a read is selected, while a logic 0 selects a write operation.

Default power-up value (ALLCALLADR register): E0h or 1110 000
Programmable through I
At power-up, LED All Call I
E0h (R/W = 0) or E1h (R/W = 1) is sent by the master.
3 different I
Default power-up values:
– SUBADR1 register: E2h or 1110 001
– SUBADR2 register: E4h or 1110 010
– SUBADR3 register: E8h or 1110 100
Programmable through I
At power-up, Sub Call I
ACK when E2h (R/W = 0) or E3h (R/W = 1), E4h (R/W = 0) or E5h (R/W = 1), or
E8h (R/W = 0) or E9h (R/W = 1) is sent by the master.
