Description

TRIGGER_LEVEL
RW
R
0
Trigger level. When the TX FIFO has less entries than
the number of this field, a transmitter trigger event is
generated:
-INTR.TX_FIFO_TRIGGER = (#FIFO entries <
TRIGGER_LEVEL)
16
CLEAR
RW
R
0
This is a synchronous clear signal to the TX FIFO.
When '1', the TX FIFO content are cleared. If a quick
clear is required, the field should be set to '1' and
followed by '0'. If a clear is required for an extended
time, the field should be set to 1 during the complete
time.
17
FREEZE
RW
R
0
Freeze functionality:
'0': HW uses TX FIFO data and pops the data from the
TX FIFO for every HW read.
'1': HW read from TX FIFO does not pop the data from
the TX FIFO.
Note: Freeze functionality is for debug purpose only.
