LINESTATE
LINESTATE
This setting allows the link to turn off the automatic SYNC and EOP generation, and must
be used for high-speed packets only. It is provided for backward compatibility with legacy
controllers that include SYNC and EOP bytes in the data payload when transmitting
packets. The ISP1506 will not automatically generate SYNC and EOP patterns when
OPMODE[1:0] is set to 11b. The ISP1506 will still NRZI encode data and perform bit
stuffing. An example of a sequence is shown in
packets using the TXCMD (NOPID) type. The ISP1506 does not provide a mechanism to
control bit stuffing in individual bytes, but will automatically turn off bit stuffing for EOP
when STP is asserted with data set to FEh. If data is set to 00h when STP is asserted, the
