Inter-integrated circuit (I2C) interface RM0367
750/1043 RM0367 Rev 7
Bit 7 ERRIE: Error interrupts enable
0: Error detection interrupts disabled
1: Error detection interrupts enabled
Note: Any of these errors generate an interrupt:
Arbitration Loss (ARLO)
Bus Error detection (BERR)
Overrun/Underrun (OVR)
Timeout detection (TIMEOUT)
PEC error detection (PECERR)
Alert pin event detection (ALERT)
Bit 6 TCIE: Transfer Complete interrupt enable
0: Transfer Complete interrupt disabled
1: Transfer Complete interrupt enabled
Note: Any of these events generate an interrupt:
Transfer Complete (TC)
Transfer Complete Reload (TCR)
Bit 5 STOPIE: Stop detection Interrupt enable
0: Stop detection (STOPF) interrupt disabled
1: Stop detection (STOPF) interrupt enabled
Bit 4 NACKIE: Not acknowledge received Interrupt enable
0: Not acknowledge (NACKF) received interrupts disabled
1: Not acknowledge (NACKF) received interrupts enabled
Bit 3 ADDRIE: Address match Interrupt enable (slave only)
0: Address match (ADDR) interrupts disabled
1: Address match (ADDR) interrupts enabled
Bit 2 RXIE: RX Interrupt enable
0: Receive (RXNE) interrupt disabled
1: Receive (RXNE) interrupt enabled
Bit 1 TXIE: TX Interrupt enable
0: Transmit (TXIS) interrupt disabled
1: Transmit (TXIS) interrupt enabled
Bit 0 PE: Peripheral enable
0: Peripheral disable
1: Peripheral enable
Note: When PE=0, the I2C SCL and SDA lines are released. Internal state machines and
status bits are put back to their reset value. When cleared, PE must be kept low for at
least 3 APB clock cycles.
