3.12 Transmitter Registers
PRBS test patterns used by RPATT [addr 041] and TPATT [addr 076] are defined in the ITU
TPATT[1:0]
standards O.151 and O.152 to use either inverted or non-inverted data. Bt8370/8375/8376 uses
standard data inversion for the selected PRBS test pattern unless ZLIMIT is enabled, in which
case the test pattern uses non-inverted data (see
