Abstract
A microcontroller unit (MCU) with a controller area network (CAN) function. The MCU provides a CAN controller for the CAN function, to generate a transmission signal (CANTX) in digital form. The MCU also has a digital signal remapping circuit inside, which remaps the CANTX signal into a first chip output and a second chip output. The MCU has a first pin that outputs the first chip output to drive a differential positive signal line (CANH) of the CAN function. The MCU has a second pin that outputs the second output to drive a differential negative signal line (CANL) of the CAN function.
