Custom Transmit Pulse Level. A zero means that the transmit pulse level is
determined by the bits TX2-0 listed in the table entry below. When CPL is a one,
the pulse level is determined by coefficients programmed in registers 1CH - 1Fh
on Page 2.
Transmit pulse amplitude. Select the TX2-TX0 bits according to the line type,
value of termination resistors (R
TX2 TX1 TX0 Line(Ω) R
