Note: When I²C Interfaces are used, each of the above listed register pages has its own 6-bit I²C device address. In order to address Page 0 to 3, the two LSBs if the pre-configured I2C1_ID are replaced with 00 for Page 0, 01 for Page 1, 10 for Page 2 and 11 for Page 3. As an example, if I2C1_ID=0x26 (0100110b) , Page 0 to 3 have following addresses:

• Page 0: 0100100
• Page 1: 0100101
• Page 2: 0100110
• Page 3: 0100111

For Page 4 the I²C device address is according register bits I2C2_ID. Therefore, in case both I²C1 and I²C2 Interfaces are used, each TPS6593-Q1 device occupies four I²C device addresses (for Page 0, Page 1, Page 2 and Page 3) on the I²C1 bus and one I²C device address (for Page 4) on the I²C2 bus. And in case only I²C1 Interfaces is used, each TPS6593-Q1 device occupies five I²C device addresses (for Page 0, Page 1, Page 2, Page 3 and Page 4) on the I²C1 bus. In case multiple devices are used on a common I²C bus, care must be taken to avoid overlapping I²C device addresses.

Note: When SPI Interface is used, the above listed register pages are addresses with the PAGE[2:0] bits: 0x0 addresses Page 0, 0x1 addresses Page 1, 0x2 addresses Page 2, 0x3 addresses Page 3
