12 Encoder Input Circuit (ENC)
<ENRUN>: ENC Run
<NR1:0>: Noise Filter
<INTEN>: ENC Interrupt Enable
Encoder pulse division

Rotation Direction Bit
Revolution Error flag
Noise filter counter
Encoder counter
Z Detected flag
Setting <ENRUN> to 1 and clearing <ZDET> to 0 enables the encoder operation.
There are counters and flags that are and are not cleared even if the <ENRUN> bit is cleared to 0.
The following table shows the states of the counters and flags, depending on the value of <ENRUN>.

The digital noise filters remove pulses narrower than the width selected by <NR1:0>.

In the other operating modes, <ZEN> has no effect.
0: Disabled
1: Enabled
Clearing <ENRUN> to 0 disables the encoder operation.
00: No filtering
01: Filters out pulses narrower than 31/fsys as noises.
10: Filters out pulses narrower than 63/fsys as noises.
11: Filters out pulses narrower than 127/fsys as noises.
0: Disabled
1: Enabled
<INTEN> enables and disables the ENC interrupt.
Setting <INTEN> to 1 enables interrupt generation. Clearing <INTEN> to 0 disables interrupt

cleared to 0 on the edge of ENCZ selected by <ZESEL>.
In Timer mode
<ZEN> controls whether to use the ENCZ signal as an external trigger input.
When <ZEN> = 1, the value of the encoder counter is captured into the EN0INT register and
