Receive FIFO Threshold Register
RX_TL | Controls the level of entries (or above) that triggers the RX_FULL interrupt (I2C_RAW_INTR_STAT[RX_FULL] bit). The valid range is 0-255, with the additional restriction that hardware does not allow this value to be set to a value larger than the depth of the buffer. If an attempt is made to do that, the actual value set will be the maximum depth of the buffer. A value of 0 sets the threshold for 1 entry, and a value of 255 sets the threshold for 256 entries. |
