LED All Call I²C Bus Address
• Default power-up value (ALLCALLADR address register): 90h or 1001 000
• Programmable through I²C bus (volatile programming)
• At power-up, LED All Call I²C bus address is enabled. TLC59208F sends an ACK when 90h (R/W = 0) or 91h
(R/W = 1) is sent by the master.
NOTE:
The default LED All Call I²C bus address (90h or 1001 000) must not be used as a
regular I²C bus slave address since this address is enabled at power-up. All the
TLC59208Fs on the I²C bus will acknowledge the address if sent by the I²C bus
master.
LED Sub Call I²C Bus Address
• Three different I²C bus addresses can be used
• Default power-up values:
– SUBADR1 register: 92h or 1001 001
– SUBADR2 register: 94h or 1001 010
– SUBADR3 register: 98h or 1001 100
• Programmable through I²C bus (volatile programming)
• At power-up, Sub Call I²C bus address is disabled. TLC59208F does not send an ACK when 92h (R/W = 0)
or 93h (R/W = 1) or 94h (R/W = 0) or 95h (R/W = 1) or 98h (R/W = 0) or 99h (R/W = 1) is sent by the master.
NOTE:
The default LED Sub Call I²C bus address may be used as a regular I²C bus slave
address as long as the SUBADRx bits are disabled.
Software Reset I²C Bus Address
The address shown in Figure 6 is used when a reset of the TLC59208F needs to be performed by the master.
The software reset address (SWRST Call) must be used with R/W = 0. If R/W = 1, the TLC59208F does not
acknowledge the SWRST. See Software Reset for more detail.

Figure 6. Software Reset Address
NOTE:
The Software Reset I²C bus address is a reserved address and cannot be use as a
regular I²C bus slave address or as an LED All Call or LED Sub Call address.
