SLLSFM9 March 2021 TUSB216I
TUSB216I supports 100 KHz I2C for device configuration, status read back and test purposes. For detail electrical and functional specifications refer to I2C Bus Specification 2.1, 2001 – STANDARD MODE. This controller is enabled after SCL and SDA pins are sampled high shortly after return from shutdown. In this mode, the CSR can be accessed by I2C read/write transaction to 7-bit slave address 0x2C. It is advised to set CFG_ACTIVE bit before changing values. This halts the FSM, and reset it after all changes are made. This ensure proper startup into high-speed mode.
