Do not insert a parity error.
Insert parity error in parity bit of receive TOH serial output for
as long as this bit is set.
Set receive direction K2 K2 bytes to 0.
Pass receive direction K1 K2 though pointer mover.
Do not insert parity error.
Insert parity error in the parity bit of receive direction parallel
output bus for as long as this bit is set.
Power down CDR channels (PWR_DN_A/B/C/
D_N=0). TOH_EN_A(or B, C, D)=0, and
DOUTA(or B, C, D)=0, can be used to 3-state out-
put buses.
Functional mode.
DOUTA(or B, C, D) _EN=0, can be used to 3-state
output bus.
Functional mode.
TOH_EN_A(or B, C, D)=0, can be used to 3-state
TOH output lines.
Description
When Rx direction OOF occurs, do not insert
AIS-L.
When Rx direction OOF occurs, insert AIS-L.
Do not force AIS-L.
Force AIS-L.
