Document ID: PMC-2010850, Issue 1

OFAV

The out-of-frame-alignment status bit (OFAV) reports the state of the frame alignment block

in the R8TD block. OFAV is set high when the frame alignment block is in the out-of-frame-

alignment state. OFAV is set low when the frame alignment block is in the in-frame-

alignment state.

OCAE

The out of character alignment interrupt enable bit (OCAE) masks the contribution of the

change of character alignment event indication bit (OCAI) in the R8TD block to INTB. When

OCAE is high, INTB is asserted low when OCAI is high. INTB is not affected by the value

of OCAI when OCAE is low.

OFAE

The out of frame alignment interrupt enable bit (OFAE) masks the contribution of the change

of frame alignment event indication bit (OFAI) in the R8TD block to INTB. When OFAE is

high, INTB is asserted low when OFAI is high. INTB is not affected by the value of OFAI

when OFAE is low.

LCVE

The line code violation interrupt enable bit (LCVE) masks the contribution of the line code

violation event indication bit (LCVI) in the R8TD block to INTB. When LCVE is high, INTB

is asserted low when LCVI is high. INTB is not affected by the value of LCVI when LCVE is

low.

FUOE

The FIFO underrun/overrun status interrupt enable bit (FUOE) masks the contribution of the

FIFO underrun/overrun event indication bit (FUOI) in the R8TD block to INTB. When

FUOE is high, INTB is asserted low when FUOI is high. INTB is not affected by the value

of FUOI when FUOE is low.

RXINV

The receive data invert bit (RXINV) controls the active polarity of the incoming data stream.

When RXINV is set high, the data is complemented before any processing by the R8TD.

When RXINV is set low, data is not complemented before R8TD processing.

Reserved[2:0]

The Reserved[2:0] bits must be set to the indicated default value for correct operation of the

NSE.
