Working mode :
1.STEP/DIR mode:
(1)SPI position welding 0Ω resistor, making the driver work in
STEP/DIR mode.
(2)Working mode selection: SDI (CFG1), SCK (CFG2)
2. SPI working mode wiring instructions:
Before wiring, it is necessary to select the hardware operation mode of
the driver module:
(1)1. Solder CFG4 and CFG5 as shown in the purple area (CFG4 is
connected to GND, CFG5 is connected to VCC); (Welding is correct to
enable spreadcycle mode)
(2)Remove the resistor at the SPI position to put the driver in SPI mode
