RXOSINTDONE Out Async Reserved.
RXPMARESET In Async This port is driven High and then deasserted to
start RX PMA reset process. In single mode,
activating RXPMARESET resets only the RX
PMA blocks not including CDR and LPM. In
sequential mode, activating RXPMARESET
starts the RX reset process as shown in
Figure 2-18 from RXPMARESET and
followed by RXCDRPHASERESET,
RXCDRFREQRESET, RXLPMRESET,
EYESCANRESET, RXPCSRESET, and
RXBUFRESET. Detailed coverage on
sequential mode is listed in Table 2-20.
RXCDRRESET In Async Reserved. Tied Low.
RXCDRFREQRESET In Async Reserved. Tied Low.
RXLPMRESET In Async This port is driven High and then deasserted to
start the LPM reset process. In single mode,
activating RXLPMRESET resets only the RX
LPM circuits. In sequential mode, activating
RXLPMRESET starts the RX reset process as
shown in Figure 2-18 from RXLPMRESET
and followed by EYESCANRESET,
RXPCSRESET, and RXBUFRESET. Detailed
coverage in sequential mode is listed in
Table 2-20.
EYESCANRESET In Async This port is driven High and then deasserted to
start the EYESCAN reset process. In single
mode, activating EYESCANRESET resets
only the RX Eye Scan circuits. In sequential
mode, activating EYESCANRESET starts the
RX reset process as shown in Figure 2-18 from
EYESCANRESET and followed by
RXPCSRESET, and RXBUFRESET. Detailed
coverage in sequential mode is listed in
Table 2-20.
RXPCSRESET In Async This port is driven High and then deasserted to
start the PCS reset process. In single mode,
activating RXPCSRESET resets only the RX
PCS circuits. In sequential mode, activating
RXPCSRESET starts the RX reset process as
shown in Figure 2-18 from RXPCSRESET and
followed by RXBUFRESET. Detailed
coverage in sequential mode is listed in
Table 2-20.
In both modes, RXPCSRESET does not start
the reset process until RXUSERRDY is High.
