Quadrature pulse and double edge evaluation
When independent 2-pulse type is engaged, + direction pulses are output through the output signal nPP, and
− direction pulses through nPM.
When 1-pulse 1-
direction type is engaged, + and − directions pulses are output through the output signal
nPLS, and nDIR is for direction signals.
When quadrature pulse type is engaged, the A-phase signal of quadrature pulse is output through the output
signal nPA, and the B-phase signal of quadrature pulse through nPB.

D7 DPINV
Replaces output pins of drive pulse output between nPP/PLS/PA signal and nPM/DIR/PB signal.
0: initial setting, 1: pin inversion
When this bit is set to 1 and pulse output type is independent 2-pulse, drive pulses are output to the nPM
signal during the + direction driving and to the nPP signal during the – direction driving. In the same way,
output pins are replaced when in other pulse output types.

Up / Down pulse input
When quadrature pulses input type is engaged and nECA signal goes faster 90 degree phase than nECB
signal does, it's "count up" and nECB signal goes faster 90 degree phase than nECA signal does, it's "count
down". And when quad edge evaluation is set, it counts Up/Down at the rising edge (
↑) and falling edge (↓)
of both signals. When double edge evaluation is set, it counts Up/Down at the rising edge (
↑) and falling
edge (
↓) of A-phase signals. When single edge evaluation is set, it counts Up at the rising edge (↑) of
A-phase signals in the Low of B-phase signal, and it counts Down at the falling edge (
↓) of A-phase signals
in the Low of B-phase signal.
When Up / Down pulse input type is engaged, nPPIN signal is for "count up" input, and nPMIN signal is for
