TMOIE Bit (Timeout Interrupt Request Enable)
This bit is used to enable or disable timeout interrupt (TMOI) requests when the ICSR2.TMOF flag is set to 1. A TMOI
interrupt request is canceled by setting the TMOF flag or the TMOIE bit to 0.
ALIE Bit (Arbitration-Lost Interrupt Request Enable)
This bit is used to enable or disable arbitration-lost interrupt (ALI) requests when the ICSR2.AL flag is set to 1. An ALI
interrupt request is canceled by setting the AL flag or the ALIE bit to 0.
STIE Bit (Start Condition Detection Interrupt Request Enable)
This bit is used to enable or disable start condition detection interrupt (STI) requests when the ICSR2.START flag is set
to 1. An STI interrupt request is canceled by setting the START flag or the STIE bit to 0.
SPIE Bit (Stop Condition Detection Interrupt Request Enable)
This bit is used to enable or disable stop condition detection interrupt (SPI) requests when the ICSR2.STOP flag is set to
1. An SPI interrupt request is canceled by setting the STOP flag or the SPIE bit to 0.
NAKIE Bit (NACK Reception Interrupt Request Enable)
This bit is used to enable or disable NACK reception interrupt (NAKI) requests when the ICSR2.NACKF flag is set to 1.
An NAKI interrupt request is canceled by setting the NACKF flag or the NAKIE bit to 0.
RIE Bit (Receive Data Full Interrupt Request Enable)
This bit is used to enable or disable receive data full interrupt (RXI) requests when the ICSR2.RDRF flag is set to 1.
