SCLS715 – MARCH 2009 Table 1. TLC59208F Address Map (continued) ADDRESS INPUT SLAVE ADDRESS A2 A1 A0 A6 A5 A4 A3 A2 A1 A0 ADDRESS SDA GND SDA 1 1 1 0 1 0 1 EAh SDA VCC SCL 1 1 1 0 1 1 0 ECh SDA VCC SDA 1 1 1 0 1 1 1 EEh • 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. • 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. 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.
