Master interrupt request
I2C_ARB_LOST | I2C master lost arbitration: the value driven by the master on the SDA line is not the same as the value observed on the SDA line. |
I2C_NACK | I2C master negative acknowledgement. Set to ‘1’, when the master receives a NACK (typically after the master transmitted the slave address or TX data). |
I2C_ACK | I2C master acknowledgement. Set to ‘1’, when the master receives a ACK (typically after the master transmitted the slave address or TX data). |
I2C_STOP | I2C master STOP. Set to ‘1’, when the master has transmitted a STOP. |
I2C_BUS_ERROR | I2C master bus error (unexpected detection of START or STOP condition). |
SPI_DONE | SPI master transfer done event: all data frames in the transmit FIFO are sent, the transmit FIFO is empty (both TX FIFO and transmit shifter register are empty), and SPI select output pin is deselected. |
