Sda hold time

Webb19 nov. 2024 · SDA must be stable for the entire HIGH period of SCL. SDA must be held for 300ns while SCL goes low. Saying "while" here seems a bit strange, but it's to emphasize the 0 + 300ns minimum needed for SCL transition back to low. Typically I believe the hold time will be (1/2*SCL period) + 300ns. WebbName: I2C SDA Hold Time Length Register Size: 24 bits Address Offset: 0x7c Read/Write Access: Read/Write The bits [15:0] of this register are used to control the hold time of SDA during transmit in both slave and master mode (after SCL goes from HIGH to LOW). The bits [23:16] of this register are used to extend the SDA transition (if any)
