23.9.41 SCB_INTR_S
Description:
Slave interrupt request
Address:
0x40600F40
Offset:
0xF40
Retention:
Not Retained
IsDeepSleep:
No
Comment:
The register fields are not retained In DeepSleep power mode: HW clears the interrupt causes
to '0', when coming out of DeepSleep power mode. In addition, HW clears the interrupt causes
to '0', when the IP is disabled. As a result, the interrupt causes are only available in
Active/Sleep power modes; they are generated by internally clocked logic (this logic operates
on a clock that is only available in Active/Sleep power modes).
The interrupt causes should only be used for internally clocked operation; i.e. EC_OP is '0'.
Default:
0x0

I2C_ARB_LOST
RW1C
RW1S
0
I2C slave lost arbitration: the value driven on the SDA
line is not the same as the value observed on the SDA
line (while the SCL line is '1'). This should not occur, it
represents erroneous I2C bus behavior. In case of lost
arbitration, the I2C slave state machine aborts the
ongoing transfer. The Firmware may decide to clear
the TX and RX FIFOs in case of this error.

I2C_NACK
RW1C
RW1S
0
I2C slave negative acknowledgement received. Set to
'1', when the slave receives a NACK (typically after the
slave transmitted TX data).
2
I2C_ACK
RW1C
RW1S
0
I2C slave acknowledgement received. Set to '1', when
the slave receives a ACK (typically after the slave
transmitted TX data).
