<ZDET>: Z Detected
<SFTCAP>: Software Capture
<ENCLR>: Encoder Counter Clear
<ZESEL>: Z Trigger Edge Select
<CMPEN>: Compare Enable
<ZEN>: Z Phase Enable
<ZDET> is set to 1 on the first edge of Z input signal (ENCZ) after <ENRUN> is written from 0 to 1. This
occurs on a rising edge of the signal Z during CW rotation or on a falling edge of Z during CCW rotation.
<ZDET> remains cleared while <ENRUN> = 0.
If <SFTCAP> is set to 1, the value of the encoder counter is captured into the EN0CNT register.
Writing a 1 to <ENCLR> clears the encoder counter to 0. Once cleared, the encoder counter restarts
counting from 0. Writing a 0 to <ENCLR> has no effect. Reading <ENCLR> always returns a 0.
<ZESEL> selects the edge of the ENCZ that should be used as an external trigger in Timer mode.
If <CMPEN> is set to 1, the value of the encoder counter is compared to the value programmed in the
EN0INT register. If <CMPEN> is cleared to 0, this comparison is not done.

0: Not detected
1: Detected
<ZEN> has no influence on the value of <ZDET>.
<ZDET> remains cleared in Sensor Event Count and Sensor Timer Count modes.
0: －
1: Software capture
Writing a 0 to <SFTCAP> has no effect. Reading <SFTCAP> always returns a 0.
In Encoder and Sensor Event Count modes, <SFTCAP> has no effect; a write of a 1 to this bit is
ignored.
0: －
1: Clears the encoder counter.
0: Uses a rising edge of the ENCZ as an external trigger input.
1: Uses a falling edge of the ENCZ as an external trigger input.
In the other operating modes, <ZESEL> has no effect.
0: Compare disabled
1: Compare enabled
0: Disabled
1: Enabled
motor is rotating in the CW direction; the encoder counter is cleared on the falling edge of ENCZ if
the motor is rotating in the CCW direction. If the edges of ENCLK (multiply_by_4 clock derived from
the decoded A and B signals) and the edge of ENCZ coincide, the encoder counter is cleared to 0
without incrementing or decrementing (i.e., the clear takes precedence).
In Encoder mode
<ZEN> controls whether to clear the encoder counter (EN0CNT) on the rising or falling edge of Z.
When <ZEN> = 1, the encoder counter is cleared on the rising edge of the ENCZ input if the
