Serial Data Input Specifications

1. Serial Data Input Setup

First set STB low and then input the SDATA and SCLK signals. The SCLK signal is not accepted when STB is high.

SDATA inputs the data in the order D0, D1, ... D6, D7.

Data is transferred on the rising edge of SCLK and after all data has been transferred, all the data is latched on the rising

edge of STB.

2. Timing with which the Serial Data Settings are Reflected in the Output

• STP timing mode (applies to microstep driver settings)

Type 1: The hold, reset, and enable settings, as well as the reference voltage setting are reflected at the same time as

the STB signal data latch operation.

Type 2: The forward/reverse (FR) and the excitation setting mode (MS) setting that are set at STP setup are reflected

in the output at the next clock rising edge after data latch.

• STB timing (applies to settings other than the above)

Type 1: The PWM driver, constant-current driver, PI, and other settings are reflected at the same time as the STB signal

data latch operation.
