to 1, the counter value can also be captured by an edge of the Z signal input selected via
<ZESEL>.
When <INTEN> = 1, the ENC generates interrupt requests, based on the counter value and the
There are six interrupt sources, depending on the operating mode, and the settings of
In Sensor Timer Count mode and Timer mode, the value of the encoder counter can be
The captured counter value can be read out of the ENCNT register.
In Sensor Timer Count mode, the value of the encoder counter is captured into the ENCNT
In Timer mode, the counter value can be captured by writing a 1 to <SFTCAP>. If <ZEN> is set
Interrupt Source
When <CMPEN> = 1, the encoderl counter
counts events (encoder pulses). When it has
reached
<EN0INT>, an interrupt occurs.
An interrupt occurs on each divided clock
pulse, which is derived by dividing the
encoder pulse by a factor programmed in
<ENDEV>.
An interrupt occurs to indicate that an event
(encoder pulse) has occurred, causing the
counter value to be captured.
When <CMPEN> = 1, the ENC uses a
counter that counts up with fsys and is
cleared by an event (encoder pulse). If no
event
programmed in <EN0INT>, an interrupt
occurs.
When <CMPEN> = 1, an interrupt occurs
when the timer has reached the value
programmed in <EN0INT>.
An interrupt occurs when the counter value
has been captured on an external trigger (Z
input).
