7. SERIAL DATA INPUT SEQUENCE
The
μ
PD168113 can control driving of two or more motors with only a few CPU signals by using a serial data input
method. The serial data is input as follows.
(1) Input addresses 0 to 2 after power up and initialization.
(2) Depending on the type of the motor set, input the necessary data of addresses 3 to F (two or more addresses may
be input).
(3) When performing the driving setting, only the necessary data of addresses 3 to F has to be input because the
previous data is retained.
Only the output related to the input address will change.
To perform an initialization operation such as selecting the motor, initialize the internal registers by using the
RESETB pin.
