Encoder Mode; Figure 3.1 Encxz Input Is Valid ([Enxtncr]<Zen>=1) - Toshiba TXZ Series Reference Manual

3.2.1. Encoder Mode

This mode supports High-speed position sensor (Phase judgment). The incremental encoder (AB and ABZ) should
be used.
●
Using the rotation edge detection, a division pulse and an interrupt can be generated.
●
Using the rotation edge pulse count, an interrupt can be generated at any counter value.
●
Rotation direction judgment
●
32-bit up- and down-count (controlled by the rotation direction judgment)
●
The setting of the counter value is available.
●
The setting of the detected rotation direction is available.
●
Abnormal state detection flag
