Cable Loss bit 5: CLOS[5:0] are the six bits receiver for selec-
tive equalizer setting which is also a binary word that represents
the cable attenuation indication within ±1dB. CLOS5 is the most
significant bit (MSB) and CLOS0 is the least significant bit (LSB).
Cable Loss bit 4: See description of D5 for function of this bit.
Cable Loss bit 3: See description of D5 for function of this bit.
Cable Loss bit 2: See description of D5 for function of this bit.
Cable Loss bit 1: See description of D5 for function of this bit.
Cable Loss bit 0: See description of D5 for function of this bit.
The shape of the transmitted pulse can be made user program-
mable by selecting "Arbitrary Pulse" mode, see
arbitrary pulse is divided into eight time segments whose com-
bined duration is equal to one period of MCLK.
This 7 bit number represents the amplitude of the arbitrary pulse
during the first time segment. B6S1 -B0S1 is in signed magni-
tude format with B6S1 as the sign bit and B0S1 as the least sig-
nificant bit (LSB).
