Chopping Frequency Setting (D6 and D7 in the serial data)
This IC integrates an internal oscillator circuit and allows the chopping frequency used in constant-current control to be
switched with the serial data (111***, D6, D7) setting.

Monitor Output Setting (Serial data bits D3, D4, and D5)
The signal output from the PI3/MO pin can be switched with the serial data (111, D3, ****) setting.

Stepping position detection monitor output
It is also possible to select which of channels 1 and 2 or channels 3 and 4 are output from the monitor pin with the serial
data (111*, D4, D5, **) setting. The MO output position used to detect the driver excitation position in microstepping
drive mode can also be switched. The state MO = Low is output at the output position.
