I use L6470H chip.
I found a issue of the chip.
I want switch mode BUSY and SYNC in my program to control of the step clocking.
I can write "1" to SYNC_EN bit of the STEP_MODE register.
BUT I can't come back STEP_MODE register to BUSY mode. I am reading "1" in SYNC_EN bit unlike I wrote "0" there before.
reg displayed 0x7e8q value . It means NOTPERF_CMD is set in "1".
Conditions: my stepper motor is stopped, any command is not executed.
How Can I switch from SYNC mode to BUSY mode in STEP_MODE register?
