23.9.49 SCB_INTR_RX
Description:
Receiver interrupt request
Address:
0x40600FC0
Offset:
0xFC0
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).
Default:
0x0

TRIGGER

0
More entries in the RX FIFO than the value specified
by RX_FIFO_CTRL.TRIGGER_LEVEL.
Only used in FIFO mode.
2
NOT_EMPTY
RW1C
RW1S
0
RX FIFO is not empty.
Only used in FIFO mode.
3
FULL
RW1C
RW1S
0
RX FIFO is full. Note that received data frames are lost
when the RX FIFO is full. Dependent on
CTRL.MEM_WIDTH: (FF_DATA_NR =
EZ_DATA_NR/2)
MEM_WIDTH is '0': # entries == FF_DATA_NR.
MEM_WIDTH is '1': # entries == FF_DATA_NR/2.
MEM_WIDTH is '2': # entries == FF_DATA_NR/4.
Only used in FIFO mode.
5
OVERFLOW
RW1C
RW1S
0
Attempt to write to a full RX FIFO. Note: in I2C mode,
the OVERFLOW is set when a data frame is received
and the RX FIFO is full, independent of whether it is
ACK'd or NACK'd.
Only used in FIFO mode.
6
UNDERFLOW
RW1C
RW1S
0
Attempt to read from an empty RX FIFO.
Only used in FIFO mode.
