RXBUF FLUSH
0-1
This bit is used to flush the receivebuffer.
If STATRES = 1:
The command RXBUF FLUSH = 1 is
ignored.
If STATRES = 0:
RXBUF FLUSH = 1 causes the flushing
of the receive-buffer.
TXBUF FLUSH
0-1
This bit is used to flush the transmitbuffer.
If STATRES = 1:
The command TXBUF FLUSH = 1 is
ignored.
If STATRES = 0:
TXBUF FLUSH = 1 causes the flushing
of the tranceive-buffer.
STATRES
0-1
This bit is set to reset the STAT bit in the
process input data.
With the change from 1 to 0 the STAT bit
is reset (from 0 to 1).
If this bit is 0, all changes in
TX_BYTE_CNT, TX_CNT and
RX_CNT_ACK are ignored.
Flushing the transmit-/ receive-buffer
with RXBUF FLUSH/ TXBUF FLUSH is
possible.
If this bit is 1 or with the change from 0
to 1, the flushing of the transmit-/
receive-buffer with RXBUF FLUSH/
TXBUF FLUSH is not possible.
