Note 6: External supply when operating in encoder mode. ENC+ IN is passed to all ENC+ lines with optional

protection diodes to prevent reverse connection.

Note 7: In single-ended mode, the PhaseA, PhaseB and Index (–) inputs at the user connector are left floating.

The (–) inputs of the differential receiver are routed to +3 V reference.

Note 8: DIO6 can also function as Timer Output 0.

Note 9: DIO7 can also function as Timer Output 1.

Note 10: CEMF protection to the DIO supply; it is not a source.
