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