Bits 14:12 – TRIM[2:0] Trim bits for DP/DM
These bits calibrate the matching of rise/fall of DP/DM.
Bits 10:6 – TRANSN[4:0] Trimmable Output Driver Impedance N
These bits calibrate the NMOS output impedance of DP/DM drivers.
Bits 4:0 – TRANSP[4:0] Trimmable Output Driver Impedance P
These bits calibrate the PMOS output impedance of DP/DM drivers.
