Note: This register configures each LIU individually. This register configures the LIU selected by TST.TST[2:0].
Bit 7: Receive Impedance Match On (RIMPON). If this bit is set, internal receive impedance matching is turned
on. Otherwise, the receiver is in high impedance. Note that the OE pin can have control instead of this bit when the
TST.RHPMC bit is set.
Bit 6: Transmit Impedance Termination Off (TIMPOFF). If this bit is set all the internal transmit terminating
impedance is turned off.
Bit 3: Transmit Impedance Receive Match (TIMPRM). This bit selects the internal transmit termination
impedance and receive impedance match for E1 mode and T1/J1 mode.
0 = 75
for E1 mode or 100 for T1 mode.
1 = 120
for E1 mode or 110 for J1 mode.
Bits 2 to 0: Template Selection [2:0] (TS[2:0]). Bits TS[2:0] are used to select E1 or T1/J1 mode, the template,
and the settings for various cable lengths. The impedance termination for the transmitter and impedance match for
the receiver are specified by bit TIMPRM. Short-haul or long-haul operation is selected by the SHLHS bit in the
individual registers SHLHS (07). See Table 6-13 for bit selection of TS[2:0].
