Rough servo/phase control automatic switching monitor output. If a high level then rough servo mode.
If a low level then phase control mode.
Reset signal input for initializing only the anti-shock control part (i.e. excluding the DSP part). Resets when
this pin is low level, and release the reset when this pin is high level. Tie this pin to the low level (i.e.,
connected to 0 V) if when using software control on the anti-shock part alone through the anti-shock part
only reset disable/release command ($F4) or the anti-shock only reset enable/inrush command ($F5).
Note: This pin is assigned as the least significant bit of the general I/O port however, use as a general I/O
pin is disabled. When the port I/O set command ($DB) is executed, the least significant bit is always “0,” and
the output driver is not turned ON.
General I/O pin 2. This controls the commands from the microcontroller. When not used, either set this as
an input port and connect to 0 V, or set this as an output port and leave it open.
