9.5.5 LED All Call I²C Bus Address
• Default power-up value (ALLCALLADR register): D0h or 1101 000
• Programmable through I²C Bus (volatile programming)
• At power-up, LED All Call I²C Bus address is enabled. TLC59116-Q1 sends an ACK when D0h (R/W = 0) or
D1h (R/W = 1) is sent by the master.
See LED All Call I2C Bus Address Register (ALLCALLADR) for more detail.
NOTE
The default LED All Call I²C Bus address (D0h or 1101 000) must not be used as a
regular I²C Bus slave address, since this address is enabled at power-up. All the
TLC59116-Q1 devices on the I²C Bus will acknowledge the address if it is sent by the I²C
Bus master.
