Bit
Description
rx_del

rx_del
0
Description: Reception delimiters. In RCV state, this pair of
bits indicates the type of delimiter which terminates the current byte. Their
configuration is shown below in Table 4.
HW Reset state: 00
Enable trigger:
Set to 11 when a PEOF symbol has been detected and received.
Set to 10 when an EOP symbol has been detected and received. Also set
to 10 after the CRC has been received and the checksum result is
available, or set to 10 when the reception timestamp bytes are being
passed to the PL-One firmware.
Set to 01 when an EOF symbol has been detected and received.
Set to 00 when 8 consecutive packet Data symbols have been saved in
Ph_Rx_Buffer before receiving an EOF or EOP delimiter symbol. This
case can happen for any packet field part, including those transmitted with
Leading Zero Suppression (LZS). Also set to 00 when a PEOF symbol
has been received but fewer than 8 Preamble symbols were detected.
This situation is likely to happen with a Medium Noisy indication (see
ch_noisy
bit).
Reset trigger: It is reset when the PLSES Handshake Interrupt is reset.
jabber (LSB)
Description: Jabber Detect. In XMIT state, it indicates that the
PL-One has transmitted at least 1,000 consecutive SUPERIOR symbols. In
RCV state, it indicates that the PL-One has received at least 1,000
consecutive SUPERIOR symbols.
HW Reset state: 0
Enable trigger: Set to 1 after the PL-One has transmitted at least 1,000
consecutive SUPERIOR symbols. Also set to 1 after the PL-One has
received at least 1,000 consecutive SUPERIOR symbols.
Reset trigger: It is reset when 1024 consecutive SUPERIOR states have
been detected on the channel in either transmission or reception.
