Bits 2 to 0: Receive Impedance Selection (RIMPM[2:0]). These bits are used to select the receive impedance
termination. They must be set according to the cable impedance even if internal termination resistance is disabled
(RIMPON = 0). See
Table 10-22. Receive Impedance Selection
19-5856; Rev 4; 5/11
Bit 6: Receive Internal Impedance Match On (RIMPON)
