・ In Encoder mode, the incremental encoder inputs of the TMPM370 should be connected to the A,
・ During CW rotation (i.e., when A leads B), the encoder counter counts up; when it has reached
・ During CCW rotation (i.e., when A lags B), the encoder counter counts down; when it has reached
・ Additionally, when <ZEN> = 1, the encoder counter is cleared to 0 on the rising edge of Z during
