23.9.45 SCB_INTR_TX
Description:
Transmitter interrupt request
Address:
0x40600F80
Offset:
0xF80
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
RW1C
RW1S
0
Less entries in the TX FIFO than the value specified by
TX_FIFO_CTRL.TRIGGER_LEVEL.
Only used in FIFO mode.
1
NOT_FULL
RW1C
RW1S
0
TX FIFO is not 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.
4
EMPTY
RW1C
RW1S
0
TX FIFO is empty; i.e. it has 0 entries.
Only used in FIFO mode.
5
OVERFLOW
RW1C
RW1S
0
Attempt to write to a full TX FIFO.
Only used in FIFO mode.
6
UNDERFLOW
RW1C
RW1S
0
Attempt to read from an empty TX FIFO. This happens
when SCB is ready to transfer data and EMPTY is '1'.
Only used in FIFO mode.
7
BLOCKED
RW1C
RW1S
0
SW cannot get access to the EZ memory (EZ data
access), due to an externally clocked EZ access. This
may happen when STATUS.EC_BUSY is '1'.
8
UART_NACK
RW1C
RW1S
0
UART transmitter received a negative
acknowledgement in SmartCard mode. Set to '1', when
event is detected. Write with '1' to clear bit.
