The UVLO, TH_WRN, TH_SD, OCD, STEP_LOSS_A, STEP_LOSS_B, NOTPERF_CMD,
WRONG_CMD and SW_EVN flags are latched: when the respective conditions make them
active (low or high) they remain in that state until a GetStatus command is sent to the IC.
The BUSY bit reflects the BUSY
pin status. The BUSY flag is low when a constant speed,
positioning or motion command is under execution and is released (high) after the command
have been completed.
The SCK_MOD bit is an active high flag indicating that the device is working in step clock
mode. In this case the step clock signal should be provided through STCK input pin. The
DIR bit indicates the current motor direction:
MOT_STATUS indicates the current motor status:
Any attempt to write to the register causes the command to be ignored and the
NOTPERF_CMD to rise (see paragraph
9.1.22).
