15.5.2.5. Interrupt Status Register (ISR)
Bit | Fields | Access | Default Value | Description |
---|---|---|---|---|
31:5 | Reserved | N/A | 0x0 | Reserved |
4 | RX_OVER | R/W1C | 0x0 | Receive overrun 1: Indicates receive data FIFO has overrun condition, new data is lost.
Note: Writing 1 to this field clears the content of the field to 0.
|
3 | ARBLOST_DET | R/W1C | 0x0 | Arbitration lost detected 1: Indicates core has lost the bus arbitration
Note: Writing 1 to this field clears the content of this field to 0.
|
2 | NACK_DET | R/W1C | 0x0 | No acknowledgement detected 1: Indicates NACK is received by the core
Note: Writing 1 to this field clears the content of this field to 0.
|
1 | RX_READY | R | 0x0 | Receive ready 1: Indicates receive data FIFO contains data sent by the remote I2C device. This bit is asserted when RX_DATA FIFO level is equal or more than RX_DATA FIFO threshold.
Note: This field is automatically cleared by the core's hardware once the receive data FIFO level is less than RX_DATA FIFO threshold.
|
0 | TX_READY | R | 0x0 | Transmit ready 1: Indicates transfer command FIFO is ready for data transmission. This bit is asserted when transfer command FIFO level is equal or less than TFR_CMD FIFO threshold.
Note: This field is automatically cleared by the core's hardware once transfer command FIFO level is more than TFR_CMD FIFO threshold.
