with an external microcontroller.
It has an on−chip voltage
regulator,
reset−output and watchdog reset, able to supply peripheral devices.
It
contains a current−translation table and takes the next micro−step depending on the clock signal on the “NXT” input pin and the status of the “DIR” (=direction) register or input pin.
The CAN transceiver is the interface between a (CAN) protocol controller and the physical bu...
