The AM261x LaunchPad internally muxes the eQEP, FSI and OSPI1 signals. The eQEP0 instance of the AM261x are terminated to two headers (J19, J16). The eQEP1 instance of the AM261x are terminated to two headers (J18, J15).

All eQEP signals have series termination resistors between the AM261x SoC and the Voltage Level Translator (TXB0108RGYR). The voltage level shifter is responsible for translating the 3.3V to 5V.
