SLVSD02E March 2015 – August 2021 TPS65982
The boot code sets the hardware configurable unique I2C address of the TPS65982 before the port is enabled to respond to I2C transactions. The unique I2C address is determined by a combination of the digital level on the DEBUG_CTL1/DEBUG_CTL2 pins (two bits) and the analog level set by the analog I2C_ADDR strap pin (three bits) as shown in Table 9-9.
|Default I2C Unique Address for Each Port|
|Port Number||Bit 7||Bit 6||Bit 5||Bit 4||Bit 3||Bit 2||Bit 1||Bit 0|
|I2C Port 1(1)||0||1||1||1||I2C_ADDR_DECODE[2:0]||R/ W|
|I2C Port 2||0||1||DEBUG_CTL2||DEBUG_CTL1||I2C_ADDR_DECODE[2:0]||R/ W|
