SLVSF34B May 2019 – October 2022 TPS65987DDJ
PRODUCTION DATA
The boot flow sets the hardware configurable unique I2C address of the TPS65987DDJ before the port is enabled to respond to I2C transactions. For the I2C1 interface, the unique I2C address is determined by the analog level set by the analog ADCIN2 pin (three bits) as shown in Table 8-2 .
Default I2C Unique Address | |||||||
---|---|---|---|---|---|---|---|
Bit 7 | Bit 6 | Bit 5 | Bit 4 | Bit 3 | Bit 2 | Bit 1 | Bit 0 |
0 | 1 | 0 | 0 | I2C_ADDR_DECODE[2:0] | R/W | ||
Note 1: Any bit is maskable for each port independently providing firmware override of the I2C address. |
For the I2C2 interface, the unique I2C address is a fixed value as shown in Table 8-3 .
Default I2C Unique Address | |||||||
---|---|---|---|---|---|---|---|
Bit 7 | Bit 6 | Bit 5 | Bit 4 | Bit 3 | Bit 2 | Bit 1 | Bit 0 |
0 | 1 | 1 | 1 | 0 | 0 | 0 | R/W |
Note 1: Any bit is maskable for each port independently, providing firmware override of the I2C address. |
The TPS65987DDJ I2C address values are set and controlled by device firmware. Certain firmware configurations may override the presented address settings.
