Abnormal input error

An abnormal input error occurs when the counter input signal changes on the A and B phases

simultaneously. Notification of the error is via a status (latch/clear), interrupt, or external output (one-

shot pulse). If the digital filter is enabled, an abnormal input error occurs when both the A and B phases

change during one period of the digital filter source clock. When the filter is disabled, an abnormal input

error occurs when both the A and B phases change during one period of the board 's 40MHz (25nsec)
reference clock.

A possible cause of the abnormal input error is as follows.

When the phase difference between phases-A and B is shorter than one digital filter source clock

cycle (25 nsec with no filter set)

Noise is generated.

Figure 4.17. Abnormal input error

Phase-A input

Phase-B input

An abnormal input error is reported if phases-A and B

change in level during the filter source clock cycle.

No abnormal input error is reported when

the phase difference is longer than the

filter source clock cycle.
