XTRIG External trigger input CLMP+ CEMF protection for DIO (Note 5)
XPCR External pacer input ENC+ IN Encoder power input(Note 2)
GND Ground GND Ground
DIO0 DIO channel 0 DIO1 DIO channel 1
DIO2 DIO channel 2 DIO3 DIO channel 3
DIO4 DIO channel 4 DIO5 DIO channel 5
DIO6* DIO channel 6 (Note 3) DIO7* DIO channel 7 (Note 4)
Note 2: External supply when operating in encoder mode. ENC+ IN is passed to all ENC+ lines with optional
protection diodes to prevent reverse connection.
Note 3: DIO6 can also function as Timer Output 0.
Note 4: DIO7 can also function as Timer Output 1.
Note 5: CEMF protection to the DIO supply; it is not a source.
