2-3. Initial Setup Logic Unit
STROBE AB
Function
Note: Do not use the TEST mode. Keep all the corresponding bits and any unused pins at a low level.
Note: The setting entered in initial setup mode is in effect if the DATA signal is low when the STROBE signal is
DATA AB
Sleep
This circuit is used to set up driver functions (initial setup) according to signals entered from the DATA pin.
The functions that can be set up include motor re-configuration, digital tBLANK, DC-DC converter ON/OFF
setting, and DC motor mode Vref (gain) setting.
CLK AB
supplied. The initial setup mode data is cleared at POR (power-on reset).
